On a yard within reach of the sea, the mirror usually outlasts the bracket holding it up. BRANZ notes that sea salt in coastal air significantly increases corrosion of metals used in construction, which is why an install here gets specified around the fixings as much as the face. Group One New Zealand fits convex safety mirrors on Timaru sites, with crews running down from our Islington base in Christchurch, 157 km up the coast. Sydney Chappell founded the New Zealand company in 2026. Tell us where the sight line fails and we will come and look at it.
Which exits and corners actually need one
Timaru is the industry hub for South Canterbury, and the freight traffic shows it. Around PrimePort and out through the Washdyke industrial belt at the State Highway 8 junction, the same handful of positions come up:
- A yard exit onto a road where the boundary fence or a parked line of trailers hides the approach
- A loading bay or roller door opening onto a lane shared with the next tenancy
- A truck turning circle inside the yard, where a trailer sweeps across a walking route
- Aisle intersections in a store or a processing plant where forklifts and people cross
- Car park corners and ramp turns in the Edwardian central city, where frontages sit tight to the footpath
- Farm and rural-commercial gateways pulling out onto open road

How the job runs when we come down
Timaru sits near the southern edge of our run, which stretches from Amberley in the north down to here, and west towards the foothills. The crew brings the ladder, the post, the auger and the levels in one trip, so we ask up front about access, ground conditions and when the yard is quiet enough to work in.
On site, the assessment happens from the driver’s eye position rather than from the footpath. Where the exit runs , the stopping point is fixed, so the mirror is sighted from there. The mirror then goes onto something already standing, a wall, a column, a gate post, an existing pole, or onto a new post we dig and set. Aiming is the last thing we do: set the tilt, sit back in the vehicle, check the view again, adjust until the approach is genuinely covered.
Salt decides the hardware
Everywhere else in Canterbury you choose the face first. Here the mount comes into it just as early.
Coastal air carries salt inland, and it goes to work on unprotected steel long before anyone notices the mirror is drooping. So on exposed Timaru positions the specification runs to hot-dip galvanised or powder-coated posts, corrosion-protected brackets, and aluminium or stainless fixings rather than plain zinc-plated hardware. A stainless steel face is the obvious partner for that, since it will not break at all and takes the weather without clouding, at a small cost to image sharpness.
Where the mirror lives indoors, or under cover in a warehouse aisle, acrylic gives the crispest image and polycarbonate absorbs the impacts that come with forklift height. The same site often needs two specifications, one for the covered aisle and one for the gate onto the road, and that is a decision made standing on the ground rather than off a product page. Formats follow the geometry: hooded faces for outdoor exits dealing with glare and driven rain, half domes for a T-junction in an aisle, full domes for a four-way crossing.
Sight line, diameter, angle
Viewing distance sets the diameter. The further back the driver sits, the larger the face has to be before an approaching truck reads clearly in it. Undersize the face and the blind spot stays exactly where it was, with everyone now assuming it is handled.
Mounting height has to clear whatever parks in front of it, and stay low enough to show road rather than roofline.
Tilt is the part that cannot be pre-set. A mirror aimed into a low morning or evening sun goes white at the hour the shift changes, so orientation and the decision on a hood get made together, on site, with someone sitting in the cab.
What a courier cannot deliver
A convex mirror can be on your doorstep tomorrow from any national supplier, and that part is genuinely simple. What no delivery includes is the judgement about which corner it belongs on, how far back from the exit, at what height, facing where, and what it can be safely fixed to in a salt-laden atmosphere. That set of decisions is the difference between a mirror that removes a blind spot and one that just occupies a wall. The face is hardware. Siting, mounting and aiming it is the service.

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.
Fences, the District Plan and Timaru District Council
Since a mirror is nearly always mounted to something else, the consent question follows the structure. Timaru District Council treats fences or walls under 2.5 metres 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 taller street-front structure can be exempt from building consent and still breach a District Plan performance standard, which is when a land use consent comes into it.
Inside your own yard, on your own building, this is generally straightforward. If the mount is a road boundary fence, or the mirror needs to look into the road corridor, confirm the position with the council before anything is dug.
What the quote turns on
Pricing is on quote, and the quote follows a site visit. What moves it:
- The number of mirrors, and whether one good position covers two problems
- Face diameter, set by the viewing distance
- Whether there is a sound structure to mount to, or a post has to be set
- Exposure, and the corrosion grade of the post, brackets and fixings
- Hooded or open face, stainless or acrylic
- Access, and whether the work fits around freight movements or waits for a quiet window

Re-aims, knocks and changed layouts
Posts get clipped, and a nudged mirror still looks fine from the ground while showing you nothing useful. Sites change as well: a new store goes up, the stacking area moves, the flow through the yard is reversed. Either way we come back out, look again from the driver’s seat, and re-angle or relocate it. We guarantee all the work we do.
The people behind Group One New Zealand
Sydney Chappell founded Group One New Zealand in 2026. We are a small team, so you know you’ll get the very best, working from Islington in Christchurch, far enough from South Canterbury that we would rather settle the whole specification in one visit than come back for a detail. 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 wider range is set out on our page.

Book a look at the site
Worth knowing before we come down: how exposed the position is, and whether anything already standing there has started to rust. That answers most of the specification question before we arrive, and the rest gets settled from the driver’s seat.

What people ask before booking
Do you need permission to put up a convex mirror?
On your own property, on your own building, usually not. It comes down to what carries it and where that structure sits. In this district the two to check are Timaru District Council’s building consent exemption for fences and walls under 2.5 metres, and the District Plan’s 2 metre cap on road boundary fences in residential and related zones.
What is the purpose of a convex safety mirror?
The curved face spreads the reflection outward, so one mirror shows a much wider arc than a flat one of the same diameter. It hands a driver, a forklift operator or someone walking a view of traffic they have no direct line of sight to, in time to stop instead of react.
What are the disadvantages of convex mirrors?
The curve that widens the view also compresses distance. A truck in a convex face looks smaller and further away than it really is, and closing speed is hard to read. Detail falls off toward the edge as well. So a mirror answers whether something is coming, not how long you have.
Will a mirror survive out near the port?
The face will. The question is always the mount, which is why the post, the brackets and the fixings get specified for the exposure rather than for the invoice.
