Reverse out of a bay in a busy town-centre car park and the thing you cannot see is usually a person, not a car. Group One New Zealand supplies and installs convex safety mirrors around Rangiora, with crews travelling up from our Islington base in Christchurch, about 35 minutes down the road. Sydney Chappell founded the New Zealand company in 2026. Point us at the bay, the corner or the exit that keeps producing near misses and we will come and look at it properly.
Town-centre car parks, trade yards and shared entrances
Rangiora is the population centre of North Canterbury, with around 19,300 people in town serving a wider catchment, and 7,458 businesses across Waimakariri in 2025. Retail and trade car parks here turn over their whole population several times an hour, which changes what a mirror is for: it is watching pedestrians and reversing shoppers as much as through traffic.
The positions we get called to:
- A car park exit onto a main street where parked vehicles hide the footpath
- Blind corners between rows, where two vehicles meet at right angles with no warning
- A trade counter or yard where customers walk across a route that trucks reverse along
- Roller door and loading bay exits onto a shared service lane
- Aisle intersections inside a store or workshop where forklifts and people cross
- A shared driveway serving several tenancies, or a right of way behind a row of shops
New building keeps adding to it. The Waimakariri District Plan unlocked land for up to 17,000 new houses across Rangiora, Kaiapoi, Woodend and Oxford, and a car park built for the town of ten years ago carries a good deal more traffic now than it was laid out for.

The visit, the mount, and the aim
Everything travels with the crew from Islington: ladder, post, auger, levels. So we ask early about access, where a post could go, and which hour of the day the car park is quiet enough to work in without closing you down.
On site the assessment happens from the driver’s eye position, in a vehicle, not from the kerb. Where a yard entrance sits behind , that position is wherever the vehicle waits for them, and the face is aimed to suit it. The mirror then goes onto something already standing (a wall, a column, a fence post, an existing pole) or onto a new post we set. Aiming is last and it is not a formality: tilt, sit back down in the driver’s seat, look again, adjust. We work the whole region on the same runs, from Amberley in the north through to Timaru in the south, and west towards the foothills.
Sizing it for the distance you actually look
Viewing distance decides the diameter. A driver leaving a bay is reading a mirror from a few metres away and needs a modest face; a driver waiting at a yard gate looking 50 metres up the street needs a much larger one before an approaching vehicle is big enough to judge. Fitting the small one to the long sight line is the most common mistake we get called out to correct.
Mounting height decides what is in shot. Too low and a parked van blocks it. Too high and you are looking at rooflines.
Then orientation. A face pointed into a low morning or evening sun goes white at the busiest part of the day, which is usually the argument for a hooded mirror on an open outdoor position rather than an unhooded one.
What a delivered mirror leaves undone
You can have a convex mirror couriered to the shop tomorrow, and the hardware will be fine. What arrives is a face, a bracket and a bag of screws. What does not arrive is the decision about which corner it belongs on, how far back, at what height, facing where, and what it can be mounted to. Get those wrong and the mirror is up, the blind spot is unchanged, and everyone stops watching for it. The choosing, the mounting and the aiming is the service; the mirror is the part that comes in the box.
A mirror that drifts is worse than no mirror at all
North Canterbury’s strongest winds come from the north-west, and Environment Canterbury projects that inland areas north and west of Rangiora could be 15 to 25% windier in winter and spring by 2090. A face that shifts a few degrees over a season still looks like a working mirror. It just quietly stops showing the approach, and nobody notices until something happens.
So the mount is specified to hold: adequate post depth and diameter for the face it carries, a bracket rated for the size rather than the cheapest that fits, and fixings torqued rather than nipped up. Larger faces catch more wind, which is one of the reasons diameter and post specification get decided together.
The same applies after a knock. A trailer clips a post, someone catches a bracket with a pallet, or the flow through your car park gets reversed and the mirror is now pointed at nothing useful. Ring us and we come back, check it from the driver’s seat again, and re-aim or relocate it. We guarantee all the work we do.

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.
Materials for an exposed North Canterbury mount
Acrylic gives the sharpest image and belongs indoors or under cover. Polycarbonate takes an impact without shattering, which suits forklift height and anywhere a load can swing. Stainless steel does not break at all and goes where knocks or interference are likely.
Formats follow the geometry: hooded for exposed outdoor exits dealing with glare, driven rain and frost; half domes for a T-junction in an aisle; full domes for a four-way crossing.
Mounts go onto walls, columns, existing posts and poles, or onto a new galvanised post. Brackets and fixings are corrosion protected, with aluminium or stainless hardware wherever the mirror lives outside through frosts and nor’westers.
Waimakariri District Council, boundaries and your neighbour
Waimakariri District Council says it becomes involved in fencing only where a fence needs a building consent or a resource consent, or where it adjoins Council land. It also advises that a resource consent is likely for any fence on a road boundary or an internal boundary. Nationally, a building consent is not required for fences or hoardings up to 2.5 metres.
There is a neighbour dimension too. Boundary fences fall under the Fencing Act 1978, which means a fencing notice and 21 days for your neighbour to respond before work starts. If the best position for your mirror happens to be a shared boundary structure, that is worth knowing before anyone climbs a ladder. Inside your own boundary, on your own building, it is generally straightforward, and we install to whatever position the council confirms.

What goes into the quote
Pricing is on quote and follows a site visit. The things that move it:
- How many mirrors the site actually needs, and whether one good position covers two approaches
- Face diameter, set by the viewing distance
- Whether there is a sound structure to mount to, or a post has to be dug and set
- Post and bracket specification, which rises with face size and exposure
- Indoor or outdoor, and the corrosion grade of the fixings
- Access, and whether we can work through trading hours
Contact us for bespoke pricing. Quotes are written, in New Zealand dollars, and come after someone has walked the site.
What Group One New Zealand is aiming at
Our vision is to create safer, more efficient parking environments for both drivers and pedestrians across New Zealand. On a town-centre car park absorbing North Canterbury’s growth, that reads as fewer surprises at the entrance rather than a longer product list. Sydney Chappell founded Group One New Zealand in 2026, we are a small team, so you know you’ll get the very best, and crews reach Rangiora from the Islington base in Christchurch. In the company’s 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.” The full range is set out on our page.

Get the corner assessed
Most of the car parks we get called to around here were laid out perfectly sensibly for the town that existed when they were built. What changed is the volume crossing them, not the geometry, and a properly sited mirror on the corner that has become the pinch point is the cheapest way to catch up with that.

Questions Rangiora businesses ask
Do you need permission to put up a convex mirror?
On your own property, on your own building, usually not. It depends on what carries it. Waimakariri District Council gets involved with fencing where a building or resource consent is needed, or where the fence adjoins Council land, and it advises that a resource consent is likely for a fence on a road or internal boundary. The national position is that fences and hoardings up to 2.5 metres do not need a building consent. If your mirror wants to sit on a boundary structure or look into the road corridor, confirm it with the council first.
What is the purpose of a convex safety mirror?
The curved face bends the reflection outward so one mirror covers a far wider arc than a flat one of the same size. It gives a driver, a forklift operator or someone on foot sight of traffic they have no direct line to, early enough to stop rather than react.
What are the disadvantages of convex mirrors?
The curve that widens the view compresses distance. Vehicles look smaller and further away than they are, and speed is genuinely difficult to judge off a convex face. Detail also drops away toward the edge. So it answers “is anything coming”, not “how long have I got”, and drivers still have to creep out and look.
How often should a mirror be checked?
Give it a look at the start of winter and again after any hard nor’wester. If the view from the driver’s seat has changed, it needs re-aiming rather than replacing.
