The washable mesh is pet-friendly and child-safe, designed to let animals and kids pass through easily while the magnets close automatically behind them.
Fly Screen Door NZ is a focused supplier dedicated entirely to magnetic fly screen door solutions for the New Zealand market. Their range caters to standard single doors, wider openings, and sliding door configurations. Heavy-duty magnets and reinforced mesh stitching ensure the screen handles the regular use of a busy household without wearing out, while the Velcro installation system means no tools, no drilling, and no damage to your door frame.
Budget Screens NZ is the go-to option for cost-conscious Kiwi homeowners who don't want to sacrifice quality. Their magnetic fly screen range covers both windows and doors, with options available under $50 — popular with renters, first-time buyers, and anyone wanting to screen a whole property without a large outlay. Magnets are strategically positioned for reliable automatic closure, and the screens can be trimmed with scissors at home to fit virtually any NZ window or door type.
Most New Zealand homes benefit from both. A magnetic door screen fits your back door, ranch slider, or kitchen entry and closes hands-free every time someone passes through. A magnetic window screen attaches to individual windows via self-adhesive magnetic strips and peels away in seconds when you need to open the window fully. Together they provide comprehensive insect and sandfly protection without any drilling, tools, or permanent modifications to your NZ home.
Standard 18x16 mesh does not stop sandflies — they are too small to be blocked by standard mesh openings. For sandfly protection in New Zealand — particularly in Fiordland, the West Coast, Marlborough Sounds, Stewart Island, and anywhere near still water in the South Island — a 20x20 midge mesh is essential. This tighter weave stops sandflies completely while still allowing excellent airflow. Simple Screens NZ and Budget Screens NZ both carry midge mesh options.
Yes — aluminium joinery is the dominant window and door frame type across New Zealand homes, and it provides an excellent adhesive surface for magnetic strip attachment. Clean the aluminium with a dry cloth before applying the self-adhesive magnetic strip, press firmly for 30 seconds, and allow 24 hours to cure. The screen frame snaps magnetically onto the strip without tools and peels away cleanly when you need to open the window.
Yes — magnetic screens are fully compliant with New Zealand tenancy law under the Residential Tenancies Act. They use no permanent fixtures and the adhesive Velcro strips remove cleanly without marking or damaging aluminium, timber, or uPVC frames. New Zealand tenants can install them without landlord permission and take them to the next property on leaving — an important consideration in NZ's tight rental market where adding home comfort is a priority.
Standard New Zealand exterior doors are typically 2040mm high by 810mm or 860mm wide — similar to Australian standard sizing. Add 2cm each side and top for the Velcro border. Ranch sliders (sliding doors) are measured by the full open aperture, not the glass panel. Older New Zealand homes often have non-standard dimensions, so always measure the actual door frame opening before ordering.
Yes — ranch sliders are extremely common in New Zealand homes and one of the primary magnetic screen applications. When the slider is open, measure the full aperture width — not just the glass panel. Wide-format magnetic door screens cover ranch slider openings effectively. The Velcro attaches to the aluminium joinery frame on each side and across the top of the opening.
The South Island West Coast and Fiordland are the most sandfly-intensive regions in New Zealand — Westland, the Haast area, Milford Sound, and Doubtful Sound have some of the highest sandfly concentrations in the country. Marlborough Sounds, Nelson Lakes, Stewart Island, and Queenstown Lakes district near water and bush are also significant sandfly areas. In these regions, 20x20 midge mesh is not optional — it is the only effective screen choice for sandfly protection.
In typical New Zealand coastal conditions, full-length centre-seam magnets hold the screen adequately. Wellington's notorious northerlies and Cook Strait winds are a different matter — for exposed Wellington properties, look for screens with a weighted bottom hem or additional magnets for wind resistance. Canterbury's nor'west and Southland's southerlies similarly require heavier magnetic sealing for reliable performance in exposed NZ locations.
Baches and holiday homes are one of the most compelling use cases for magnetic screens in New Zealand. Holiday homes near lakes, rivers, and the coast — where sandflies and mosquitoes are most active — benefit enormously from effective door and window screening. The no-drill installation means no permanent modification to the property structure, and screens can be removed and stored when the bach is not in use.
Yes — with preparation. Timber joinery in pre-1980s New Zealand homes needs to be painted, smooth, and dry before applying adhesive strips. If the paint is peeling or the timber is bare, prime and repaint first. Many older NZ villas, bungalows, and state houses have original timber window and door frames that work well with magnetic screens once the surface is in sound condition.
Yes — cats and dogs push through the centre seam and the magnets close automatically behind them. This eliminates the need for a separate pet door in many NZ households. Very popular with New Zealand dog owners who want their pets to move freely between the garden and the house during summer without propping the door open and letting in flies and sandflies.
Yes — mosquitoes are present across the North Island, particularly in Auckland, Bay of Plenty, and Waikato during summer. Standard 18x16 mesh stops New Zealand mosquitoes effectively. A magnetic door screen with full-length centre-seam magnets combined with magnetic window screens on bedroom windows significantly reduces mosquito entry during the evening and overnight hours when NZ mozzies are most active.
Yes — Simple Screens NZ (simplescreens.co.nz) offers cutaway mesh samples that let you test mesh quality, colour, and density before committing to a full purchase. This is particularly useful when deciding between standard and midge mesh for your specific NZ location, or checking that the frame colour matches your aluminium joinery colour.
No — quality fly mesh reduces airflow by less than 5%. New Zealand's mild summers make open-window ventilation the primary cooling mechanism for most NZ homes, which have no air conditioning. Magnetic screens allow the fresh New Zealand breeze through freely while blocking the insects that come with it — particularly valuable in the many New Zealand homes where open windows and doors are the only summer cooling strategy.
Awning windows — which open outward from the bottom — are common in New Zealand homes. Apply the adhesive magnetic strip to the inner face of the fixed aluminium frame surround, not the moving sash. The screen covers the window opening and peels away when you want to crank the awning window open. This works with both standard and louvered awning windows common in New Zealand residential construction.
Yes — particularly for lower-floor Auckland, Wellington, and Christchurch apartments near parks and waterways. The no-drill installation means no breach of body corporate rules. Magnetic window screens on bedroom and living area windows allow apartment residents to sleep with windows open in summer without mosquitoes and flies. Magnetic door screens on balcony doors provide hands-free insect control for apartment outdoor access.
Yes — all major New Zealand online magnetic screen suppliers deliver nationwide including South Island addresses. Delivery to rural South Island and remote locations like the West Coast, Fiordland, and Stewart Island may take longer — typically 5-10 business days. Most suppliers dispatch within 1-3 business days with North Island and main South Island centres receiving delivery in 2-5 business days.
New Zealand state houses typically have timber joinery in older builds and aluminium joinery in more recent construction. For older timber-frame state houses, ensure the window and door surrounds are painted and smooth before applying adhesive strips — repaint if needed. For aluminium-joinery state houses, the installation is straightforward. Simple Screens NZ provides guidance on frame types and sizing for NZ state house configurations.
Monthly during the NZ insect season — November through March across most of New Zealand. Machine wash cold on a gentle cycle with mild detergent and hang to dry. Store screens from May through September rather than leaving them on doors and windows through the New Zealand winter. Annual storage and reinstallation adds very little time and significantly extends screen lifespan.
Yes — wide-format magnetic screens cover the large sliding door openings increasingly common in New Zealand new-build homes. Modern NZ houses designed around indoor-outdoor living frequently have very wide sliding door systems opening to decks and gardens. Measure the full aperture when the doors are slid back and order the appropriate wide-format screen. Some suppliers provide side-by-side installation guidance for very wide openings.
Magnetic screens are excellent for campervans, motorhomes, and portable shelter applications at NZ campsites. Lightweight and fold-flat, they install on vehicle door frames without permanent modification. For DOC huts with fixed structures, magnetic screens can be applied to door frames using the standard Velcro system. The midge mesh (20x20) is the correct choice for any West Coast or Fiordland campsite application.
Yes — New Zealand conservatories and sunrooms typically have aluminium framing that is ideal for magnetic screen adhesive strips. Conservatories and sunrooms get warm in NZ summer and the impulse to open doors for ventilation is strong — a magnetic screen on the door provides effective insect control while allowing the breeze through. Standard mesh is usually adequate unless the sunroom is in a sandfly-prone location.
Simple Screens NZ (simplescreens.co.nz) leads for window screens — premium mesh quality including midge mesh for sandfly protection, sample availability, and comprehensive sizing for NZ aluminium joinery. They operate as a division of Caruso Consulting Co Ltd with an Auckland CBD base and NZ-wide delivery. Magnetic Screen NZ (magneticscreen.co.nz) is the strongest alternative with specialist expertise in unusual NZ window configurations including arched and tilt-turn windows.
Wellington's northerlies are among the strongest urban winds in the world and present a genuine challenge for any magnetic door screen. Full-length centre-seam magnets perform better than spaced magnets in wind, but for exposed Wellington properties — particularly in the Karori, Newlands, and Strathmore areas with full northerly exposure — a weighted bottom hem and reinforced side edges are strongly recommended. Ask your supplier about wind-resistant options before ordering for Wellington use.
Yes — timber sash windows in New Zealand villas and bungalows (pre-1940 housing) are compatible with magnetic screen installation. Apply the adhesive magnetic strip to the inner face of the fixed timber window surround, not the moving sash. The screen peels away when you want to slide either sash open. Ensure the timber surround paint is in good condition — repaint if peeling before applying adhesive strips.
Significantly. New Zealand's summer nights are warm enough to want bedroom windows open for ventilation, but mosquitoes and sandflies in many regions make this impractical without screening. Magnetic window screens allow windows to stay open all night for airflow while blocking insects completely, resulting in cooler sleeping temperatures and no 3am mosquito encounters. A genuine quality-of-life improvement through the NZ summer months.
Yes — significantly cheaper than professionally fitted traditional aluminium-framed screen windows or security screen doors, requiring no installation cost, and lasting multiple NZ summers with proper care. Budget Screens NZ (budgetscreens.co.nz) provides reliable screens at accessible price points for whole-home coverage. For investment-grade quality in NZ conditions, Simple Screens NZ is worth the modest premium over budget alternatives.
New Zealand has some of the highest UV radiation levels in the world due to its geographic position beneath the ozone hole and clear atmospheric conditions. UV-stabilised fibreglass mesh is essential for NZ conditions — it holds up to years of NZ summer sun without degrading. Nylon mesh deteriorates within 1-2 NZ summers. Choose fibreglass or Phiferglass mesh from all major NZ suppliers for adequate UV resistance in New Zealand conditions.
For most NZ back door and ranch slider applications, yes. A magnetic mesh screen provides equivalent insect protection to a traditional hinged fly screen door at a fraction of the cost, without professional installation, and without the bang on closing. For front entry doors where security and durability are primary concerns, a traditional security screen door remains the better option — magnetic screens prioritise convenience and affordability over security.
New Zealand is, by any reasonable measure, one of the most beautiful countries on earth — and also home to some of the most persistent and irritating insects on the planet. The New Zealand sandfly is legendary. Fiordland tourists learn about it before they arrive. West Coasters know it from the moment they open a door or window in summer. And while sandflies dominate the conversation, New Zealand's mosquitoes — active across the North Island in particular — are a serious enough nuisance to ruin a warm evening without effective protection. Magnetic screen doors and window screens are the most practical solution available for New Zealand homes in 2026, and this guide covers everything you need to know to choose and install the right one for your specific situation.
New Zealand has some specific characteristics that make it different from the UK, Australia, or other markets where magnetic screens are popular. The sandfly problem requires a different mesh specification than standard insect mesh. The dominance of aluminium joinery across New Zealand housing makes installation straightforward. The bach and holiday home culture creates a use case that is distinctly Kiwi. And New Zealand's extreme UV intensity — among the highest in the world — makes mesh material selection genuinely important for longevity.
This is the most important point for any New Zealand buyer to understand: standard 18x16 insect mesh does not stop New Zealand sandflies. The West Coast sandfly (Austrosimulium australense) and related species are substantially smaller than a mosquito — small enough to pass through the openings in standard fly screen mesh without difficulty. If you are in Fiordland, on the West Coast, in the Marlborough Sounds, near Stewart Island, or anywhere in the South Island near water and bush, standard mesh will not protect you from the biting insects that matter most in your environment.
The solution is midge mesh — also called fine mesh or 20x20 mesh. This has a tighter weave at 20x20 threads per square inch versus the standard 18x16, creating openings too small for sandflies to pass through while still allowing adequate airflow. The airflow reduction compared to standard mesh is minimal and imperceptible in normal use, but the sandfly protection it provides is complete.
Midge mesh applies to both door screens and window screens. A midge mesh door screen on your back door or ranch slider, combined with midge mesh window screens on any windows you leave open near sandfly-prone areas, provides comprehensive sandfly protection. Simple Screens NZ (simplescreens.co.nz) and Budget Screens NZ (budgetscreens.co.nz) both carry midge mesh options across their product ranges. If you are in any doubt about whether your location warrants midge mesh, the answer is almost certainly yes if you are in the South Island and within a few kilometres of water or bush.
In the North Island, mosquitoes are the primary concern rather than sandflies — standard 18x16 mesh handles mosquitoes effectively. For Auckland, Waikato, Bay of Plenty, and Hawke's Bay properties away from sandfly habitat, standard mesh is the appropriate and more economical choice.
New Zealand's housing stock is diverse — from pre-1940 villas and bungalows with original timber joinery, to the state houses of the 1950s-70s with timber or aluminium frames, to the aluminium-joinery homes of the 1980s-2000s, to today's modern new-builds with large sliding door systems and aluminium thermally broken joinery. Magnetic screens work across all of these, with slightly different installation approaches depending on the frame material.
Aluminium joinery — dominant in New Zealand homes from the 1980s onward and still the standard for new construction — is the best adhesive surface for magnetic screen installation. Clean with a dry cloth, apply the adhesive magnetic strip firmly, and allow 24 hours to cure. The bond is reliable and long-lasting on aluminium frames, and the strip removes cleanly without damage when needed.
Timber joinery in older New Zealand villas, bungalows, and state houses requires the timber to be painted, smooth, and dry. If the paint is peeling or the timber is bare — common in older NZ housing stock that has not been recently painted — prime and repaint before applying adhesive strips. Many New Zealand heritage properties have original timber sash windows with the characteristic Kiwi villa proportions, and these are fully compatible with magnetic window screens once the frame surface is in good condition.
Ranch sliders deserve specific mention as the most common magnetic door screen application in New Zealand. The ranch slider — a sliding aluminium door — is an almost universal feature of New Zealand residential construction from the 1970s onward. When fully slid open, it creates a wide aperture that is the primary access point between indoor and outdoor living spaces, and the primary insect entry point throughout summer. Measuring this full opening (not just the glass panel width) and ordering the appropriate wide-format screen is the key step for ranch slider installation.
No guide to magnetic screens in New Zealand would be complete without addressing the bach. New Zealand's batch culture — the network of modest holiday homes near beaches, lakes, and rivers across both islands — creates a specific and compelling use case for magnetic insect screens.
Baches near water are, almost by definition, in high-insect environments. A bach in the Marlborough Sounds is surrounded by sandfly habitat. A bach at Lake Taupo is in mosquito territory. A bach on the West Coast near Hokitika or Greymouth is in some of the most sandfly-intensive habitat in the Southern Hemisphere. These are exactly the locations where effective door and window insect screening makes the difference between a comfortable summer holiday and one spent fighting insects constantly.
Magnetic screens are ideal for the bach context for several practical reasons. They install without permanent modification to the bach structure — important when many baches are co-owned or have specific heritage or resource consent restrictions. They can be removed and stored when the bach is not in use, reducing UV and weather degradation through the periods when the property sits empty. They cost far less than professionally fitted traditional screen doors and windows. And midge mesh options ensure they actually stop the sandflies that make certain NZ bach locations challenging.
New Zealand sits at a latitude where the ozone layer is relatively thin and atmospheric conditions are typically clear — the result is UV radiation levels significantly higher than comparable latitudes in the Northern Hemisphere. New Zealand's UV index regularly reaches 13 or above in midsummer — classified as "extreme" — and the cumulative UV exposure experienced by a screen left in place through a New Zealand summer is substantial.
This matters for magnetic screen mesh selection. Nylon mesh — used in the cheapest magnetic screens — becomes brittle, discoloured, and structurally compromised after one or two New Zealand summers of direct UV exposure. Polyester holds up better but still shows visible degradation after two or three seasons in high-UV NZ conditions. Fibreglass mesh, and particularly Phiferglass — the premium fibreglass coated with protective vinyl used by Simple Screens NZ — is the appropriate choice for New Zealand conditions. It is UV-stable across years of use, maintains its mesh density, and does not shrink, crack, or discolour under NZ summer UV.
Practical advice: when storing screens between NZ summer seasons, keep them inside rather than in a garden shed or under a deck where UV still penetrates. Wash screens monthly during the season and hang to dry in shade rather than direct New Zealand sun. These habits, combined with UV-stable mesh, will give a NZ magnetic screen a lifespan of three to five seasons rather than one or two.
Wellington deserves its own brief section because its wind conditions create a magnetic screen challenge not faced by most other New Zealand cities. Wellington's northerlies — and the Cook Strait winds that funnel between the North and South Islands — are among the strongest regular urban winds in the world. Standard magnetic door screen sealing that works perfectly in Auckland or Christchurch may be insufficient in an exposed Wellington property.
For Wellington homeowners, look specifically for magnetic door screens with a weighted bottom hem that prevents billowing in wind, full-length magnets rather than intermittent, and reinforced side edge stitching. Contact your chosen supplier and explain your Wellington location — most will be able to advise on the most appropriate product for windier NZ conditions. In extremely exposed Wellington locations, a traditional hinged fly screen door with a latch may ultimately be more reliable than a magnetic curtain screen in the strongest conditions.
