Speed humps come up in Rolleston, Selwyn District, for the reason they come up in every town that grows faster than its roads: drivers keep meeting people on foot in places nobody designed for either. A hump is a raised profile across a lane, formed into the surface or fixed on top of it, shaped so crossing at speed is uncomfortable. They belong on treated residential streets, at crossing points, and inside private car parks, yards and accessways. The decision follows the ownership. Selwyn District Council controls the public road and assesses on safety evidence. On land you own or manage, the call is yours with nothing to lodge. Group One New Zealand designs, manufactures and installs traffic calming, with crews running out from Foremans Road in Islington, Christchurch. Sydney Chappell founded the New Zealand company in 2026.
What Selwyn District Council is doing about speed
The council’s Safer speeds, smarter growth programme is applying reduced speed limits and traffic-calming treatments to roads including Goulds Road, Lincoln Rolleston Road, Selwyn Road, Dunns Crossing Road and East Maddisons Road as the town spreads out around them.
Notice what that programme is: limits and treatments together. A lower posted limit is often the first tool an authority reaches for, because it costs nothing to maintain and slows every vehicle on the length of road rather than at one point. A physical device goes in where the limit alone is not doing the work. If you want a hump on a public Rolleston street, that request goes to Selwyn District Council, and it gets weighed on traffic and safety grounds against those other options.

Two owners, two answers
The kerb line decides who you are talking to. Beyond it, the road is Selwyn District Council’s, so the timing, the treatment and the evidence are all theirs. Inside your boundary, none of that applies. A private car park, an internal road through a business park, a body corporate accessway, a school ground or a farm approach is the owner’s to decide. You choose whether a hump goes in, exactly where it sits, and what it is built from. There is no consent, no consultation and no queue, which is usually a surprise to people who have spent a fortnight reading council pages.
Build it in while the surface is still being formed
Most of Rolleston’s housing went up between 2010 and 2019 and the town has not stopped, with subdivisions like Acland Park and Faringdon still spreading and IZONE Southern Business Hub anchoring the commercial side. The population sits around 34,100 and grows roughly 4% a year against a national 0.7%.
That means a great deal of surface around here is new or about to be poured. Calming formed as part of a car park or yard while it is being built sits flush with the falls, drains properly and never looks like an afterthought. The same job on a finished slab is a bolt-down unit, which does the job well but arrives after somebody has already had a fright. If a layout is at drawing stage, that is the cheapest moment this will ever be.
Choosing between the devices
- Full-width humps: car park aisles and entrance approaches where every vehicle should slow.
- Speed cushions: routes used by trucks and buses, which straddle the cushion instead of taking the full hit.
- Raised tables and raised pedestrian crossings: where people cross between buildings or between a car park and a door.
- Modular rubber and bolt-down units: sound asphalt or concrete that is staying where it is.
- Deployable and temporary units: events, staged works and layouts that will change again.
- Formed asphalt or concrete profiles: permanent, and shaped into the surface as it is laid.
Frost is worth a mention on the plains. A cold, damp surface on a winter morning is no place to be bonding or sealing anything, so installations shift later into the day through the frost months and we will tell you when a booked start would give you a finish you would not accept.
The sites we get called to around Rolleston
IZONE yards where trucks and forklifts share a route with people walking between buildings. Retail and hospitality forecourts on the main approaches. Schools and early learning grounds. Body corporate and retirement village accessways in the newer developments. Rural and lifestyle block entrances where the driveway is long enough to build up real speed before the house. A good many of those entrances are already on , which fixes the point a vehicle starts from.

Great job and no complaints!
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.
What a quote depends on, and what happens after you call
Everything is quoted per site. The figure moves on the device and how many, the surface it fixes into or is formed onto, access and when we can have the area, traffic volumes and vehicle types, drainage, the marking and signage around it, and whether anything needs reinstating.
Then it runs as design, manufacture and installation. Design starts with a visit and a measure-up. Manufacture covers the units or profiles for that layout. Installation covers the fixing or forming, making the surface good, and marking the hump so it is visible before a driver is on it.
Group One New Zealand, Islington to Selwyn
A town still under construction can have calming formed into a car park while the surface is going down, instead of cut into it two years later, and that is the job we would rather be called for. Site visit, design, manufacture, installation, all run from Islington in Christchurch, a short trip south-west to Rolleston in the Selwyn District. Sydney Chappell founded the company in 2026 and it is a small team. Goulds Road, Dunns Crossing Road and the rest of the public network remain Selwyn District Council’s business under its safer-speeds programme. The long service record is Australian, and the company does not dress it up: “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 lists what goes down.

Get the order of work right
If your car park is still being built, the sequence matters more than the calendar: form the surface, put the calming in while the plant is on site, then mark and sign around it. Done in that order it is one mobilisation and one finished job. Done later it is three visits and a patched slab.

Questions from Rolleston sites
The road through our business park is private. Do we need council permission?
No. On privately owned and managed roads and car parks the owner decides. Selwyn District Council’s process applies to the public road network.
How long does it take to install speed humps?
A bolt-down unit on a prepared surface is a short job, often the same visit as the measure-up if the site is straightforward. A formed profile needs curing before traffic crosses, and the crew gives you that time on the day.
What are speed humps called in New Zealand?
Judder bars. The words hump, bump and judder bar all get used for the same device.
Is there a difference between a speed bump and a speed hump?
In use, barely. If a distinction is being drawn, a bump is short and abrupt and a hump is longer and gentler. Neither term is a specification.
How fast should I go over one?
At the speed the device was designed for, which will feel obvious. The road’s posted limit still applies either way.
What are the downsides?
Noise and vibration where heavy vehicles cross, slower emergency access, and wear on suspension. On a private site those are all placement decisions, which is why we would rather walk the route than pick a spot off a plan.
