A guest who arrived after dark reverses a rental out of your driveway at eight the next morning, onto a road they have used exactly once. That is a different visibility problem from the one your own staff have quietly learned to work around. Group One New Zealand supplies and installs convex safety mirrors around Methven, with crews travelling out from our Islington base in Christchurch. Sydney Chappell founded the New Zealand company in 2026. Tell us which exit worries you and we will come and look at it.
Drivers who have never used your exit before
For a township of roughly 1,500 to 1,700 permanent residents, Methven carries an unusually large short-stay pool: holiday homes, apartments, lodges, farm stays and backpacker accommodation, filling up through the Mt Hutt season. That changes what a mirror is doing. Regulars learn a blind corner. Visitors meet it once, in an unfamiliar vehicle, often with a boot full of gear and a windscreen still fogged.
The exits that come up:
- An accommodation driveway onto a township street, where a hedge, a fence or parked cars hide the approach
- A hospitality or retail car park exit where people are walking past on the footpath
- A blind corner between rows in a car park that fills and empties in bursts
- A service yard or delivery bay at a lodge or cafe, where a truck reverses across a guest route
- A farm gateway or stockyard entrance onto a rural road
- A light industrial or service site on the Business D land along Line Road
Speeds through town have come down. NZTA cut the SH77 section at the north end of the township from 100 to 60 km/h, running past the entrance to the thermal pools. That helps, but a slower approach still has to be seen, and the traffic mix in winter includes vehicles with roof boxes, trailers and drivers watching for a turnoff rather than for you.

Booking the crew before the season starts
Everything travels out with the crew from Islington in one trip: ladder, post, auger, levels. The practical advice for Methven is to get the visit in before the season rather than during it, both because the ground is easier to work and because a driveway is far simpler to close for an hour in a quiet week.
On site we assess from the driver’s eye position, sitting in a vehicle at the exit, because a mirror set from the footpath rarely serves the person who actually needs it. A driveway with on it holds every driver in the same spot, familiar with the exit or not, which makes that assessment simpler. It then mounts to something already standing, a wall, a fence post, a column, an existing pole, or to a new post we dig and set. Aiming is the last thing and it is done from the seat: tilt, look, adjust. The same crews cover the region from Amberley in the north to Timaru in the south, and west towards the foothills.
Where the mirror goes, and how big
Diameter follows viewing distance. A short township driveway needs a modest face; a farm gateway looking a long way up a straight road needs a much larger one before an approaching vehicle is big enough to read at all.
Height has to clear whatever parks in front of it, which on a guest driveway can be different every day of the week.
Orientation matters more here than most places because of who is using it. An unfamiliar driver will only find the mirror if it sits where their eye already goes, so we set it in the natural line of sight for someone easing forward, not in the tidiest spot on the fence. A face aimed into a low morning sun goes white at exactly checkout time, which is usually the argument for a hooded format on an open exit.
The part that isn’t in the carton
A convex mirror can be delivered to the door from any national supplier, and the hardware is generally fine. What arrives is a face, a bracket and fixings. What does not arrive is the judgement about which side of the exit it belongs on, how far back, at what height, facing where, and what will hold it through a season. That decision is the whole value. A mirror in a plausible-looking position leaves the danger in place while persuading everyone it has been dealt with. Choosing the spot, mounting it and aiming it is the service.
Frost, snow and a face you can actually see through
Methven sits at about 320 m, close to the foothills, and township forecasts through winter run to overnight temperatures below freezing with rain turning to snow. That has two consequences for an outdoor mirror.
The first is material. Stainless steel faces will not break and shrug off weather; polycarbonate takes an impact without shattering, which suits anywhere a vehicle or a load can reach it; acrylic gives the sharpest image and is best kept indoors or under cover. A hooded format keeps some driven rain and low sun off an exposed face.
The second is practical. Any outdoor mirror can carry frost or a film of road grime on a bad morning, so we prefer positions a staff member can actually reach to wipe, rather than perfect sight lines four metres up a pole. Mounts go onto walls, existing posts and poles, or a new galvanised post, with corrosion protected brackets and aluminium or stainless fixings.

Wonderful to work with and helping us get our line marking completed. Would definitely use again and refer to others.
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.
Ashburton District Council, fences and retaining walls
The mirror seldom raises a consent question by itself. What holds it can, and on the sloping sites around here retaining walls come into it more often than they do out on the flat.
Ashburton District Council states you can build a fence up to 2.5 m in height from natural ground level, and recommends talking to the Planning Department about a resource consent for anything over 2 m. A fence on top of a retaining wall needs a building consent where the retaining wall is more than 1.5 m and the fence more than 2.5 m, and if the fence and the retaining wall are joined, a building consent is required.
Inside your own boundary, on your own building, this is usually straightforward. If the mount is a boundary structure or the mirror has to look into the road corridor, confirm the position with the council first and we will install to what they allow.
What shapes the quote
Pricing is on quote and follows a site visit. What moves it:
- How many mirrors the site needs, and whether one face covers two approaches
- Diameter, set by the viewing distance
- Whether there is a sound structure to mount to, or a post has to be dug and set
- Outdoor exposure, and the corrosion grade of the fixings
- Hooded or open face, and the face material
- Access, and whether the work fits into a quiet week or has to happen mid-season
Contact us for bespoke pricing. Quotes are written, in New Zealand dollars, and come after someone has walked the site.

Knocks, re-aims and the end of the season
Mirrors get clipped, particularly on a driveway used by people who have never reversed that vehicle before. Ring us and we come back, straighten it and re-aim it.
Sites change too. A deck goes in, the parking layout is reworked over summer, a hedge grows into the sight line. Same answer: we come back out, look again from the driver’s seat, and re-angle or relocate it. We guarantee all the work we do.
Where Group One New Zealand’s experience actually sits
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 New Zealand end of that is newer and a good deal smaller: Sydney Chappell founded Group One New Zealand in 2026, and we are a small team, so you know you’ll get the very best. That team travels up from Islington in Christchurch, so the trip is worth planning around your quiet weeks rather than your busy ones. The rest of the range sits on our page.

Get a look before winter
One thing is worth knowing before you book. When a second mirror goes up at the same exit, it is almost never because the first was the wrong hardware. It is because the first was aimed for the owner, in the vehicle they drive every day, rather than for a guest sitting higher or lower in a rental they collected yesterday. Say which vehicles actually use the exit and you are far less likely to be ringing us back mid-season.

Questions from lodges, farms and cafes
Do you need permission to put up a convex mirror?
On your own property, on your own building or an existing compliant structure, usually not. It depends on what carries it. In this district the figures to know are Ashburton District Council’s 2.5 m fence height from natural ground level, its recommendation to talk to the Planning Department above 2 m, and the building consent triggers where a fence sits on or joins a retaining wall. If the mount is on a boundary or the mirror needs to see into the road, ask the council first.
What is the purpose of a convex safety mirror?
The curved face spreads the reflection outward, so one mirror shows a far wider arc than a flat one of the same size. For a driver who does not know your exit, it turns a blind pull-out into a look-and-wait, which is the whole point.
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 hard to judge from a convex face. Detail also falls away at the edges. So it answers whether something is coming, not how long you have, and a driver still needs to edge out and look for themselves. That is worth a small sign beside the mirror on a guest driveway.
When is the best time to have one installed?
Outside the winter peak, if you have the choice. The ground is easier to work, the driveway is easier to close for an hour, and the mirror is in place and aimed before the first guests arrive.
