A north-westerly works on a gate in a way it never works on the fence beside it, because the leaf is the one part of a boundary that has to keep moving. That is where the specification for most security gates in Rangiora starts. Where the posts land on a shared line, the neighbour has a say in the timing as well. Group One New Zealand designs, manufactures and installs them for North Canterbury properties, with crews travelling up from Islington in Christchurch, and Sydney Chappell started the New Zealand company in 2026. Phone us on 027 424 0600, 7am to 3pm Monday to Friday, and we will come and look at the opening.
The kind of gate this page is about
This is a fabricated leaf hung at a property entrance: a driveway, a yard, a lifestyle-block gateway, a commercial frontage. Steel, aluminium or timber, on posts set into the ground, either swinging or sliding. It is not a retail security door or a window grille, which belong to a different trade with different hardware. It is not the release gate that software teams run in a build pipeline, which shares the term and nothing else. Everything described here is made in New Zealand and installed on a Canterbury site by the crew that built it.

Wind is the sizing problem out here
Canterbury’s strongest winds blow from the north-west, and Environment Canterbury projects that inland areas north and west of Rangiora could become 15 to 25% windier in winter and spring by 2090. On a fence that is a nuisance. On a gate it is a design input, because a leaf is the one part of a boundary that has to keep moving.
Three decisions follow from it. Hinge sizing, because every gust that hits the leaf is transferred through the hinge pins. Post size and footing depth, because the hinge simply passes the load down. And infill, because a solid panel catches all of it while vertical bar, palisade and welded mesh let it through without becoming easier to climb. Slatted aluminium sits between the two and lets you choose how much you see through.
It is also the reason a lot of exposed openings up here end up on a slider rather than a swing gate. A sliding leaf is not being held out in the air on two hinges, and it does not have an arc that a gust can slam shut. Where there is boundary length to park the leaf against, a ground track works. Where the ground is uneven or gets churned up, a cantilever slider carries the leaf clear with no track to keep clean. Bi-folds cover the openings with neither arc room nor run-back, and a separate pedestrian gate beside the vehicle leaf keeps people out of the way of it.
Talking to the neighbour before the posts go in
If the gate and its posts sit on a boundary you share, the Fencing Act 1978 sets the process, and it is worth following even when you and your neighbour get on. Where they will not discuss it or will not agree with what you propose, you must give them a Fencing Notice before any work begins, and give them 21 days to respond. Twenty-one days is not a long delay if you start it early. It is a very long delay if you discover it the week the steel is ready.
Waimakariri District Council and the road boundary
Waimakariri District Council takes a narrower role in fencing than some of its neighbours. It becomes involved only where a fence needs a building consent or a resource consent, which is likely to also require the written approval of the affected neighbour, or where the fence adjoins Council land.
The trigger to watch is position rather than height. The Council advises that a resource consent is likely for any fence on the road boundary or on an internal boundary, and a street-front gate sits on the road boundary by definition. Nationally, a building consent is not required for fences or hoardings up to 2.5 metres high, and pool and spa barrier gates sit outside that exemption entirely with their own requirements. Confirm what applies at your address with Waimakariri District Council before the job is priced or started.
How the leaf is put together
Frame section is sized to the leaf, so a wide vehicle gate carries considerably heavier box section than a personnel gate, and on an exposed opening it is sized for the wind load as well as the weight. Infill is welded or mechanically fixed into the frame rather than screwed to its face.
Hinges carry anti-lift detail so the leaf cannot be raised off its pins, and exposed fixings are tamper-resistant. Drop bolts land in ground sockets on double swing gates. Locking points are placed to suit the leaf height rather than sitting at handle level by default, and ground clearance under the leaf is kept tight. Posts are footed for the leaf weight and the ground they stand in. Steel is hot-dip galvanised and then powder coated, so the protection sits under the colour. Where an anti-climb head is wanted, that is extended vertical bar, a raked top or a rolled edge.

Highly Recommend Group 1 Linemarking!
We recently hired Group 1 Linemarking for a few of our residential strata projects, and the results exceeded our expectations. The team was punctual, professional, and clearly experienced. The line marking was crisp, precise, and done exactly to spec. Communication throughout the process was smooth, and they were flexible with scheduling, which made things a lot easier on our end. If you need reliable, high-quality line marking services, I wouldn’t hesitate to recommend Group 1. Great job!
Working with Syd and his team is always a pleasure
The quality of work is always to a high standard. The Group One team is always professional, they apply a high standard for safety ensuring their SWMS is tailored for the job and their equipment is serviced and well maintained. I highly recommend Group One and if you use them you won’t be disappointed.
Timber, steel, aluminium and stainless steel
Our range of materials covers wood, steel, aluminium and stainless steel. Steel gives the stiffest frame and is the honest answer where the brief is heavy duty. Aluminium is lighter, so it works the hinges, posts and footings less, and that weight saving is worth real money on a long leaf in a windy spot. It does not rust. Stainless goes into fixings and exposed fittings. Timber suits an older Rangiora frontage and moves with the seasons, so it holds up best as infill on a steel or aluminium frame rather than as the structure carrying the load.
Exposure is a line item, not a footnote
The figure is on quote. What separates one North Canterbury entrance from another is usually how exposed it stands, because gust loading sets hinge size, post size and footing depth, and it decides whether solid infill is available to you at all. On a sheltered internal driveway that input barely registers. On an open frontage facing the nor’wester it is the single biggest thing in the specification.
Sitting alongside it are the clear opening width, the gate height, the frame section and infill profile, the locking points and drop bolts, the ground conditions and fall across the opening, the leaf weight, and the finish.
Older frontages add one more. Where a gate is already hung and the fence line is sound, we look at whether the existing posts and footings can carry a new leaf sized for the wind, and often enough they cannot. That changes the scope of the work, so it gets settled at the visit and written down rather than discovered later.
Design, manufacture and installation follow. Made in New Zealand, hung by the crew that welded it, and the work is guaranteed with after-sales service to match.

Group One New Zealand, and who signs off the drawing
Sydney Chappell founded Group One New Zealand in 2026. It is a small team, and on an exposed North Canterbury site that has a practical consequence: gust loading, hinge size and footing depth get settled by the people who will be standing at the opening, instead of passing from whoever quoted the job to a bench that never saw it. Leaves are made at Islington and brought up to Rangiora finished, sized for the worst day rather than the calm morning we happened to measure on. Any longer record is an Australian one, and the company itself words it like this: “Although Group 1 Line Marking has just started here in New Zealand, as a group we have been operating in Australia for almost 25 years.” The page covers the rest.
Size the gate for the gust, not the day you measure it
The gates that are still square in fifteen years are the ones where the hinges, the posts and the footings were specified for the worst wind the opening will see, not the weather on the day someone stood there with a tape. Tell us how exposed your entrance is and we will build to that.

Questions Rangiora owners ask
What do security gates cost in Rangiora?
Quoted per site. Opening width, height, frame and infill spec, hardware, ground conditions and finish all move the figure, and an exposed opening usually needs more hinge and footing than a sheltered one.
What does heavy duty actually mean on a gate?
Heavier frame section, larger hinge assemblies, deeper footings and more locking points. It is a specification, not a product line, and it comes from the width, the weight and the exposure.
Can we have a wooden gate on a windy section?
Timber infill on a metal frame, yes. A full timber leaf on a wide, exposed opening will work its hinges hard and start to drop out of square sooner than you would like.
Does the council need to know about our driveway gate?
Quite possibly, because it is on the road boundary and that is where a resource consent is likely. It is a short phone call to the Council and worth making before the design is settled.
