A steel leaf across the top of a driveway has to work for the guest arriving at nine at night, the cleaner on Tuesday morning and the owner who lives two hours away. That is the everyday brief for security gates in Methven, where a large share of the housing is let short-stay and stands empty between bookings. Group One New Zealand fabricates and installs those gates, with crews travelling out to mid Canterbury 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 out and measure the entrance.
A steel gate, not a software gate
Worth settling early, because the words are shared. This page is about a physical gate: a fabricated leaf, made from steel, aluminium or timber, hung on posts concreted into the ground at the entrance to a property, that swings or slides to open a driveway or a yard. It is not a release gate in a software build pipeline, which uses the same two words for an approval step in a deployment process. It is not a retail security door, a window grille or a shopfront shutter either. If you are here about a gate you can put your hand on, this is the right page.

Gates on a property you are not living in
Turnover is the design constraint. An entrance used by a rotating set of guests, cleaners and tradespeople is worked far harder than a family driveway, and every one of those people needs to get in without the owner being there.
A few things follow from that. A separate pedestrian gate with its own lock means the vehicle leaf stays shut while people come and go on foot. Locking points get specified for how the gate will actually be used rather than for how it looks on a drawing, and self-latching detail matters when the last person through is in a hurry with a bag in each hand. Ground clearance under the leaf is kept tight so the gate closes to the same line every time. There is also new work in town rather than only replacements: bare Business D zoned land on Line Road allows light industrial, service and commercial development, so some Methven gates are the first ever hung at that entrance.
Frost heave, snow load and a rising ground line
Methven sits at about 320 metres near the foothills of the Southern Alps. Overnight temperatures drop below freezing and rain turns to snow, and the ski fields above the town take icy winds and storm systems right through winter. Three consequences land on a gate.
Footings go deeper than a town job needs, because frost heave lifts shallow posts and a lifted post throws a gate out of square permanently. Snow and ice add real weight to a leaf, especially a solid or close-boarded one, which is another reason a ventilated profile earns its place here. And ground tracks freeze and pack with grit, so a cantilever slider carrying the leaf clear of the ground is often the better call on a driveway that has to work in July.
Ground line matters too. On a driveway that climbs away from the road, a swing leaf has to clear rising ground through its whole arc, which either limits the swing or forces the gate onto a slider. That is a measurement question, and it is why the crew comes out before anything is drawn.
Ashburton District Council, measured from natural ground level
You can build a fence up to 2.5 metres in height from natural ground level. Above 2 metres, the Council recommends talking to its Planning Department about whether a resource consent is needed. On sloping ground the phrase “from natural ground level” does the heavy lifting: the same gate can be compliant at the low end of an opening and over height at the top, so the measurement is taken at the point that matters rather than averaged.
A fence on top of a retaining wall needs a building consent where the retaining wall exceeds 1.5 metres and the fence exceeds 2.5 metres, and a joined fence-and-retaining-wall structure needs a building consent outright. Pool and spa barrier gates are separately regulated and never covered by a general exemption. Boundary structures shared with a neighbour sit under the Fencing Act 1978. Confirm the current position with Ashburton District Council before the job is priced or started.
It is also a small township that pays attention to what goes in on its street frontages. The district has had public argument over hardware on public land, and the state highway through the north end of town has been dropped from 100 km/h to 60 km/h. None of that changes the rules for a gate on private property, but a design that sits comfortably on the street is a design that attracts fewer questions.
How the leaf is built
Frame section is sized to the leaf, so a wide vehicle gate carries much heavier box section than a personnel gate. 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.
Infill choice is a weather decision as much as a privacy one. Solid sheet and close-boarded timber catch the wind and hold snow. Vertical bar, palisade and welded mesh shed both and stay difficult to climb. Slatted aluminium sits between the two. Steel is hot-dip galvanised and then powder coated, and where an anti-climb head is wanted that means 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 takes the widest openings. Aluminium is lighter, so the hinges, posts and footings work less over the life of the gate, and it does not rust. Stainless goes into fixings and exposed fittings, which are the parts an alpine winter finds first. Timber suits a lodge or holiday-home entrance and moves with the seasons, so it lasts best as infill on a metal frame rather than as the structure.
Working out the figure for an alpine entrance
Nothing here is priced off a list. The site visit comes first, and these are the inputs it collects:
- Footing depth, set below frost heave for the ground actually present at the hole rather than to a habitual number.
- Leaf weight, which on a solid or close-boarded profile has to allow for snow and ice sitting on it.
- Clear opening width and gate height, measured against a ground line that usually climbs away from the road.
- Gate form: swing pair, track slider or cantilever, with the cantilever earning its keep wherever a track would ice up.
- Frame section, infill, locking points, latching detail, and the pedestrian gate that keeps arriving guests off the vehicle leaf.
- Finish, plus access and timing, because a booked-out property and frozen ground both narrow the window we can work in.
Design, manufacture and installation then run in that order. The gate is made in New Zealand, hung by the crew that made it, and backed by a warranty and after-sales service.

Group One New Zealand, and who actually turns up
When the owner is away from the property for most of the year, the question worth asking is who arrives at the gateway. It is our own crew, driving inland from Islington in Christchurch with the leaf fabricated, footings worked out for frost depth and posts cut for a ground line that climbs. Nothing gets handed off to somebody local at the last minute, because there is nobody local in the arrangement. One crew quotes it, builds it and hangs it. Group One New Zealand has existed since 2026, when Sydney Chappell started it, and the outfit is small enough that you would know the faces by the second visit. Experience beyond 2026 is Australian, and the company puts no gloss on it: “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 has the full range.
Book it for the shoulder, not the season
Post holes and concrete do not enjoy frozen ground, and a Methven property is hardest to work on in the weeks it is fullest. Autumn and spring are the easy windows here. If you are thinking about a gate for next winter, the sensible time to have us out is well before it.

Questions from Methven owners
What do security gates cost in Methven?
Quoted per site. Opening width, height, frame and infill spec, hardware, ground conditions and finish all move the figure, and footing depth on a frost-prone site is part of it.
Will a sliding gate work through a Methven winter?
A cantilever slider will, because there is no ground track to ice up or fill with grit. A track-mounted slider needs the track kept clear.
Can we have a timber gate on a holiday house?
Yes, as timber infill on a steel or aluminium frame. A full timber leaf takes on water and snow weight and will start to drop on its hinges sooner.
Our driveway climbs from the road. Does that rule out a swing gate?
Not always, but it decides the swing direction and the clearance under the leaf. It is the first thing measured on site, and on a steep rise a slider is usually the cleaner answer.
