Speed humps in Kaiapoi have been approved, respaced, shifted along the kerb and, in one street, supported for removal. That paper trail tells you more about how these things work than any product listing. A hump is a raised profile formed or fixed across a lane so that crossing it at speed is uncomfortable, and you meet them on residential streets a council has treated, at crossing points, and inside private car parks and yards. Which of those you are standing on decides who gets a say. On a public Kaiapoi street the decision belongs to Waimakariri District Council. Inside your own boundary it belongs to you, and there is no application to make. Group One New Zealand designs, manufactures and installs traffic calming, with crews running up from Foremans Road in Islington, about twenty minutes down the motorway. Sydney Chappell founded the New Zealand company in 2026.
What the council actually did on three Kaiapoi streets
Old North Road is the clearest case. Waimakariri District Council approved Watt’s profile speed humps there as part of a neighbourhood greenway, then widened the proposed spacing after residents pushed back, to around 200 m on the straighter sections and 150 m where visibility is poorer. Spacing was the argument, not the device.
On Sidey Quay, alongside the shared path project, staff made minor adjustments to the proposed hump locations so residents could still park outside their own properties. On Silverstream Boulevard the complaints were noise and vibration, and after weighing those against the safety case the Kaiapoi-Tuahiwi Community Board supported removing certain humps.
Three streets, three different answers. If you want one on a public road here, the request goes to Waimakariri District Council, and it is assessed on traffic and safety grounds rather than on how many people ask.

Where the decision changes hands
The kerb is the line. Everything beyond it is Waimakariri District Council’s road, so a hump out there runs on the council’s evidence and the council’s timetable, with a community board somewhere in the middle of it. Everything inside your boundary is yours to decide. A private car park, a yard, a service lane, an internal road through a body corporate or a retirement village: the owner says yes, picks the spot and picks the profile. That is the whole approval process on private land, and it is why most people who land here end up talking about their own site.
The three questions that decide whether a hump works
Kaiapoi’s public projects turned on exactly the questions a car park owner has to answer, minus eighteen months of consultation.
Where does it go? A hump placed where drivers have not yet built up speed does nothing, and one placed on top of a parking bay or a loading position annoys the people using the site every day. Walk the route a driver takes from the entrance and put it where the speed is. If the entrance is controlled by , that route starts at the point vehicles clear them.
What will it sound like? Noise and vibration are the objections that get humps taken out, and they get worse with heavy vehicles and hard profiles. If a delivery truck crosses at 6am next to a bedroom window or an office wall, that belongs in the decision before anything is fixed down.
Can you undo it? On a private surface, yes. A bolt-down unit can be lifted and relocated if you have put it in the wrong place. A formed asphalt or concrete profile is a permanent commitment, which is the trade for a longer life under heavy traffic.
Matching the device to what crosses it
The vehicles decide, not the catalogue. Full-width humps suit car park aisles and entrance approaches where everything should slow. Speed cushions leave a gap for wide-axle vehicles to straddle, so trucks and emergency vehicles are not pounded on every pass. Raised tables and raised pedestrian crossings lift the surface where people cross, so they walk at kerb level. Modular rubber and bolt-down units fix straight onto sound asphalt or concrete. Deployable units cover events and works. Formed asphalt or concrete profiles are the permanent option where the surface is being reworked anyway.
Kaiapoi sites where you can just decide
Much of the town was rebuilt after the earthquakes, so the stock is largely modern and a good deal of it was laid out before anyone knew how drivers would use it. The commercial base runs to industrial units of roughly 70 to 400 square metres, retail frontages and offices, and the district reached 69,800 people by June 2025, a lot of whom drive south in the morning and back through town at night.
The sites we get called to are yards where forklifts and trucks share a route with people on foot, car parks behind retail frontages where the through-traffic uses them as a shortcut, school and early learning grounds, body corporate accessways, and farm or lifestyle block entrances on the edge of town.

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.
What a quote turns on, and how the work runs
Everything is on quote. The figure moves on the device and how many, the surface it is fixed into or formed onto, access and when we can have the area, the traffic volumes and vehicle types crossing it, drainage, the marking and signage that goes around it, and whether anything needs reinstating afterwards.
The work runs in three stages: design, manufacture and installation. Design begins with a site visit and a measure-up. Manufacture covers the unit or profile for that layout. Installation includes making good the surface and marking the hump so a driver sees it before they feel it.
Group One New Zealand on the North Canterbury run
Waimakariri consulted for months before it moved humps on Sidey Quay, and before the community board backed removing some on Silverstream Boulevard. On land you hold, the same questions of placement, noise, vibration and what happens if it turns out wrong get worked through in an afternoon with whoever is doing the installing. That is the part Group One New Zealand handles: design, manufacture, installation, crews running north from Islington in Christchurch. It is not a big outfit and it is not an old one; Sydney Chappell founded it in 2026. Anything longer belongs to the Australian arm, as the company itself puts 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 covers the devices.

Try one before you commit to six
The sensible way into this on a private site is one unit, in the place you think the speed is, fixed down and lived with for a few weeks. If it is in the wrong spot you move it. If it works, we come back and do the rest of the route to match.
Phone us on 027 424 0600 or email info@groupone.co.nz, 7am to 3pm Monday to Friday. Have the address, the surface, and what sort of vehicles use it. Group One New Zealand, Unit 1, 37 Foremans Road, Islington, Christchurch 8042. NZBN 9429053752833.

Questions we get asked in Kaiapoi
What are speed humps called in New Zealand?
Judder bars, mostly. Speed hump, judder bar and speed bump all get used for the same thing in conversation.
What is the maximum height a speed hump can be?
That depends on the road controlling authority and the device, and there is no single figure we will quote you for a public road. For a Kaiapoi street, ask Waimakariri District Council. On your own site the profile is chosen for the vehicles crossing it, and we specify it as part of the design.
Do speed humps damage shocks or tyres?
Crossed at the speed they were built for, a well-placed hump is hard on neither. Taken fast, or laid with too abrupt a profile for the traffic, they punish suspension and that is when the complaints start.
Can a hump be taken out again if it does not work?
On private land, yes. Bolt-down units come up and relocate. Silverstream Boulevard is the reminder that even a council-installed hump is not necessarily permanent.
What are the real downsides?
Noise, vibration, slower emergency access and wear on vehicles. They are the reason we would rather spend an hour on your site than pick a spot off a plan.
