A speed hump is a raised section formed across a lane so that crossing it at any real speed is uncomfortable, which is why traffic drops to a crawl at a school gate or a crossing point. Around Christchurch you meet them in three sorts of places: on residential streets the city council has treated for safety, at crossings where the whole road surface has been lifted into a raised table, and inside private car parks and yards where an owner decided paint alone was not slowing anyone down. Who decides which one you get depends entirely on where the tarmac stops being yours. On a public road, Christchurch City Council does. On land you own or manage, you do, and nobody has to approve it. Group One New Zealand designs, manufactures and installs traffic calming from a base on Foremans Road in Islington. Sydney Chappell founded the New Zealand company in 2026.
Who decides where a hump goes on a Christchurch street
Christchurch City Council is the road controlling authority for the city’s streets, and it has put in speed humps, raised tables and raised pedestrian crossings as part of its road safety work, mostly at intersections, near schools and at crossing points. In Bromley the humps went in alongside pedestrian refuges, upgraded lighting and new road markings rather than on their own, which is how the council tends to use them: one part of a treatment, not the whole treatment. NZ Transport Agency guidance in its Traffic Control Devices Manual puts vertical deflection devices among the most effective ways to bring vehicle speeds down and make things safer for people walking and cycling.
There is a wrinkle worth knowing before you ring anyone. In April 2026 the council paused work on new speed hump projects while it settles a policy under tighter national rules, so nothing new is being approved on public streets in the meantime. A request still goes to the council, and it gets weighed on traffic and safety grounds rather than on how many neighbours signed it.

The road outside, and the car park inside
Draw a line at your boundary and the answer changes completely. The street beyond it belongs to Christchurch City Council, so a hump out there is the council’s call, made on its own timetable and its own evidence. Everything inside the boundary is yours. A private car park, a service lane behind a building, a loading yard, an internal road through a body corporate or a retirement village: on all of those the property owner decides whether a hump goes in, where it sits and what it is made of. A basement ramp behind sits on the same side of that line, and where vehicles queue at the gate is part of working out where the hump belongs. No consent, no consultation, no waiting list. That is usually the answer people are actually looking for.
Which device solves which problem
The word “hump” covers a family of devices, and they are not interchangeable.
- Full-width humps: the standard answer for a car park aisle or an entrance approach where every vehicle should slow.
- Speed cushions: laid so wide-axle vehicles can straddle them, which suits routes where trucks, buses or fire appliances have to get through without being pounded.
- Raised tables and raised pedestrian crossings: the surface is lifted at a crossing point, so people walk across at kerb level instead of stepping down into traffic.
- Modular rubber and bolt-down units: fixed to an existing asphalt or concrete surface, and the practical choice when you want calming without reforming the pavement.
- Deployable and temporary units: for events, works zones and anywhere the traffic pattern only exists for a fortnight.
- Asphalt or concrete profiles formed in place: permanent, and shaped to the fall of the surface around them.
Forklifts, tankers, refuse trucks and low-slung cars all argue for different answers, and so does whether the surface has to drain across the line you are putting the hump on.
Christchurch sites where the owner makes the call
The rebuilt central city is now mostly apartments and townhouses rather than standalone houses, and each one arrives with an access lane, a basement ramp or a shared car park that people walk through as well as drive through. That is where a driver taking the ramp at speed meets someone carrying shopping, and where the owner or the body corporate can act without asking anyone. The same goes for industrial and transport yards, school and early learning grounds, retail and hospitality forecourts, and farm or plant approaches out on the plains.
The city has an urban population of 407,800, and business locations across Canterbury grew 2.4% in the year to August 2025, the highest rate in the country. A good share of that growth arrives as a car park nobody has set out yet.
What the quote depends on, and how the job runs
Pricing is on quote, because the number moves on things you can only see standing on the site: which 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 line marking and signage that goes around it, and whether anything has to be reinstated afterwards.
We work in three stages: design, manufacture and installation. Design starts with a site visit and a measure-up, looking at where drivers actually build up speed rather than where a hump would be tidy. Manufacture covers the unit or the profile for that layout. Installation is the day itself, including reinstating the surface and marking it so the hump is visible before a driver is on top of it.

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.
Group One New Zealand, out of Islington
Christchurch is the one town in this series where the base and the job sit in the same city. Islington is on its western edge, so coming to look at a car park here is a short trip rather than a run out of town. That changes nothing about who decides on a public street: the humps, raised tables and raised pedestrian crossings appearing around the city are Christchurch City Council’s work. It does change what is possible on an apartment accessway, a basement ramp or a private forecourt, where the owner decides and we install. Sydney Chappell founded the company in 2026, and the team is small. Trading history further back than that is Australian, described by the company like this: “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.” Full range on the page.
While the council works out its policy
New humps on Christchurch streets are on hold until the council lands its new rules. Nothing about that touches the surface inside your own boundary, where the decision has always been yours and can be made this week.
Phone us on 027 424 0600 or email info@groupone.co.nz, 7am to 3pm Monday to Friday. Have the site address, the surface type and a rough idea of what crosses it. Group One New Zealand, Unit 1, 37 Foremans Road, Islington, Christchurch 8042. NZBN 9429053752833.

What people ask us about judder bars
Is a judder bar the same thing as a speed hump?
Yes. Judder bar is the everyday New Zealand name for it, and you will hear both used for the same device.
What is the difference between a speed bump and a speed hump?
In conversation the two get swapped freely. Where people do draw a line, a bump is the short, abrupt one you meet in a car park and a hump is the longer, gentler one on a road. Neither word is a specification, so what matters is the profile you choose for the vehicles crossing it.
How fast should I drive over one?
The posted limit for the road still applies. A hump is shaped to feel wrong above the speed it was built for, so if it is comfortable, you are going about the right speed.
Why do people complain about them?
Noise and vibration from heavy vehicles crossing, slower emergency response, and wear on suspension. Fair objections, all of them, and the reason placement matters more than the device.
Can a hump go in a basement or a covered car park?
Yes, and it is a common ask under apartment buildings. A bolt-down unit suits a finished concrete deck, and the decision is the owner’s or the body corporate’s.
How long does an installation take?
A bolt-down unit on a prepared surface is usually a short job. A formed profile needs curing time before traffic crosses it, and the crew gives you that on the day.
