Salt gets into the track long before it gets into the leaf. Group One New Zealand designs, manufactures and installs commercial gates in Timaru, and marks out and equips the car park and yard behind them, with the crew running down from our Islington base in Christchurch. Sydney Chappell started the New Zealand company in 2026. Phone us on 027 424 0600 or email info@groupone.co.nz, 7am to 3pm Monday to Friday, and we will come down, look at the site and talk the solution through before anything is quoted or built.
This is an exposed coastal location where airborne sea salt accelerates corrosion of construction metals. On a commercial gate that shows up in the moving parts and the electronics well before the frame gives any trouble.
The list worth specifying properly is short: rollers, track, hinges, fixings, the motor housing and the controller enclosure. A leaf that has been hot-dip galvanised and powder coated will outlast a set of untreated rollers by years, and a controller in a poorly sealed box on the seaward side of a post will fail while everything around it looks fine. So steel gets galvanised inside the sections and then coated, stainless goes into fixings and fittings, and aluminium is worth considering for a high-cycle leaf because a lighter gate asks less of the rollers that are corroding anyway.
Our range of materials covers wood, steel, aluminium and stainless steel, and we hold larger commercial motors for heavier custom leaves. All our gates are 100% New Zealand made and installed by the same team, which is where the saving sits.

Around the port and out at Washdyke, the entrance is the start of a route that runs through a weighbridge, a hardstand, a loading door and a staff car park, usually with people crossing it. We do that whole route, not just the gate at the front of it:
A worked example. A food-processing site puts in a cantilever gate on the truck entrance; the same visit sets a marked pedestrian route from the staff car park to the amenities door that never crosses the tanker path, a convex mirror on the blind corner at the chiller end, and bollards on the switchboard the forklifts pass twice an hour. One crew, one mobilisation, one set of drawings. Our vision is to create safer, more efficient parking environments for both drivers and pedestrians, and on a working plant that means the vehicle route and the foot route are designed against each other rather than one at a time.
Span first, then side room, leaf weight, duty cycle, and what has to fit through. Sliding gates on a track need a clear run alongside the opening and a track the heavy vehicles will be crossing, which is worth thinking about where stock trucks and container units run over it all day. A cantilever free-spans the opening and leaves the ground clear, which is often the better answer for exactly that reason. Single and double swing gates suit lighter traffic with room to arc, a bi-fold suits a tight frontage, and a boom or barrier arm covers a staff car park where the job is managing vehicles rather than securing a yard.
The vehicles set the clear width: a van and a ute with a trailer is one specification, a forklift crossing between buildings, a stock truck or a container unit is another.
Motors are sized to leaf weight and to how many times a day the gate moves. Around the port and the industrial belt that count is high, with heavy vehicles cycling a gate hundreds of times a week, and duty rating is the specification that decides whether you are calling anyone out in year two.
Access control runs on keypads, remotes, intercoms, card and fob readers, access controllers and remote locks, mixed so staff, contractors and drivers each get their own way in. Safety devices go on every automated gate. Solar runs a gate where there is no mains supply at the post. We also retrofit motors, controllers and hardware to gates already on site, and our safety devices and alternative opening methods allow automatic gates on sloped ground as well as flat-level. If your site is irregular, tight or hard to reach, that is a conversation rather than a problem.
There are two rules here and they do not line up, which catches people out on a street-front gate.
Timaru District Council treats fences or walls less than 2.5 metres high as exempt building work. Separately, the Timaru District Plan caps road boundary fences at a maximum height of 2 metres in its residential and related zones. So a 2.2 metre gate on a road boundary can be exempt from building consent and still breach a District Plan performance standard, which means a land use consent. A gate on a road boundary is the case most likely to trigger a rule of that kind, and boundary obligations with a neighbour come from the Fencing Act 1978.
Our equipment and installations are built to meet local requirements. The consent position belongs to the site, so confirm the current requirements with Timaru District Council before work starts.

A South Canterbury job goes on the schedule as a planned run, with the yard marking, the bollards and the mirrors loaded onto the same truck as the gate. The New Zealand company was founded by Sydney Chappell in 2026 and is deliberately a small team, so you know you’ll get the very best. In its own words: “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.” All the work is guaranteed, and every gate the team builds carries a comprehensive warranty and full after-sales service, which near the port is a maintenance relationship rather than a piece of paper.

The useful habit on a coastal site is to treat the gate like plant rather than like a fence: a look at the rollers, the track, the fixings and the controller seals on a set interval, before something seizes on the morning a truck is waiting. We build that into the after-sales service rather than waiting for the call.

The motor duty rating, the roller and track specification, and the manual release your staff can actually operate. A domestic-rated unit on a plant gate is a false economy.
It is quoted per site. Span, leaf weight, corrosion protection, groundwork, motor duty, power and access control all move the figure, so the visit comes before the number.
Yes. Timaru is the southern end of the area our crews cover, which runs up to Amberley and west towards the Canterbury foothills.
