No power at the road, a gateway set well back from the house, and a tanker due before anyone is up. That is why gate access systems in Darfield tend to start with the supply question rather than the gate. Solar with battery backup, SIM-based remote release, keypad or PIN entry, remote transmitters, Bluetooth and mobile-phone entry, an access controller holding the user list, intercom-style entry, and free-exit and safety devices are the pieces; which you need depends on what is being controlled and who has to get through. Group One New Zealand designs, manufactures and installs them, with crews heading west from our Islington base in Christchurch, and Sydney Chappell started the New Zealand company in 2026. Phone us on 027 424 0600, 7am to 3pm Monday to Friday, and we will walk the gateway with you and put a written quote in front of you.
When there is no cable at the gateway
Roughly half of Darfield’s property base is lifestyle blocks rather than town sections, and many of those entrances sit a long way from the nearest switchboard. Trenching a cable to the road is often the most expensive line on a quote, and sometimes not practical.
Solar is the usual answer. A panel and a battery run the drive and the controller, keep the running cost off your power bill, and remove the trench. Sizing is what has to be right: daily cycles, the winter run of dull days, and the reserve you want when the sun has not done its job. The battery earns its keep either way, carrying a mains gate through an outage and being the whole supply on a solar one. Behind both sits manual release, so somebody can free the gate by hand and drive out whatever has happened to the power.

Opening a gate when you are nowhere near it
Fonterra’s $500 million milk processing plant sits in the town, tankers and trucks move through the district daily, and contractors turn up on their own schedule. Somebody has to let them in, and that somebody is usually in a paddock, in a shed, or in Christchurch.
- SIM-based remote access. The controller answers a call or text from a known number and the gate opens, from anywhere with a signal.
- Mobile and Bluetooth entry. The driver’s phone becomes the credential, issued and withdrawn from the controller.
- A credential issued to the carrier rather than the person, so it survives a change of driver.
- Intercom-style entry where somebody genuinely is on site to answer.
One caution matters more here than in town: SIM-based access depends on coverage at the gate, not the house. A dwelling with three bars and a gateway with none is a common pairing, so we check the signal at the entrance.
What actually gets fitted
The leaf is the visible part. The system is everything behind it:
- A drive matched to the gate. Sliders and swing gates take different hardware, and both are sized against the weight and span of the leaf, not the opening width.
- An access controller: the part holding users, deciding what each credential opens, and letting you add or remove someone without touching the gate.
- Remote locks, so the gate is held shut when it should be.
- Free-exit detection and safety devices, so a vehicle inside can always leave and the gate stops for anything in its path.
- Alternative opening methods for ground that is not flat, which on a rural entrance it frequently is not.
Darfield sits under the nor’west arch, and the Foehn wind behind it is dry enough to lift the temperature several degrees in an hour before a cold southerly takes over in winter. That loads a tall solid leaf hard, so the drive is sized for wind as well as weight, and it drives dust into anything unsealed.
Retrofitting a farm gate that has been standing for years
A gate that still swings or slides properly is a perfectly good starting point, and a large share of what we do is automating one rather than selling a replacement. We carry parts, hardware, access controllers and remote locks for that work. On a farm gateway the assessment runs in this order:
- The posts and hinges first. A post that has leaned a degree or two since the day it went in will not hold a powered leaf square, and on a slider the track and rollers give you the same verdict faster.
- Then the ground. Gravel entrances shift, and a leaf that cleared all summer can catch after a wet week. A slope is workable using safety devices and alternative opening methods, but the fall gets measured, not eyeballed.
- Then weight and span. Farm gates are built heavy and wide, and span matters more than owners expect, because leverage on the hinge grows with it.
- Then somewhere to put everything. Drive, controller, battery and panel all want a home clear of a truck and trailer, and the panel needs sun as well as space.
Where the gate is past it, that is what you will be told, and why.
Selwyn District Council, and where the Fencing Act takes over
Selwyn District Council advises that any fence more than 2 metres tall will require a building consent and may require a resource consent, and lists fences or walls higher than 2.5 metres, plus all swimming pools and their associated fences, as needing building consent. A gate is generally read alongside the fence it sits in, and pool barriers sit outside any exemption.
On urban sections the Selwyn District Plan carries its own fencing rules on height and visibility, at Rules 4.13 and 4.17. Boundary fences are separate again: the council notes their construction and maintenance is generally governed by the Fencing Act 1978 and sits outside its jurisdiction, so what you owe a neighbour comes from the Act. Confirm current requirements with Selwyn District Council before work starts.

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.
Codes, remotes and a crew that changes with the season
Shearing gangs, harvest contractors, the stock agent, the vet. Rural access lists move through the year, so the question at specification is how easily a credential is added or removed in six months, not how many you need today. Issued individually, a contractor who has finished comes off the list and nobody else needs a new code. Moving hardware also wants servicing, because a drive cycling through dust and frost is a wearing part.
Where the money goes on a Malvern gateway
Pricing is on quote, and out here the supply line is nearly always the item that moves it furthest. A gateway within easy reach of a cable prices one way. A gateway several hundred metres from the nearest switchboard prices another, and choosing between a trench and a panel with a battery sized for a dull winter week is a real decision with a real number attached to it. Everything else falls in behind: the drive that the weight and span of the leaf demand, retrofit or new build, the entry methods and how many, the credentials the controller has to carry, the protection specified on outdoor hardware against dust and frost, and the run west.
The work runs design, manufacture, installation. Design happens at the gateway itself, with the opening measured, the gate assessed, the distance to power paced out and the signal checked where it matters. We build it ourselves and install it ourselves, 100% New Zealand made, with timber, steel, aluminium and stainless steel all on the table and a larger commercial motor behind a heavy farm leaf. Installation closes with somebody on the property walked through adding a credential and cancelling one, and a comprehensive warranty and full after-sales service stand behind the job.

Group One New Zealand, and the run west
Thirty-five kilometres of it, which is the honest description of how this works: a small team based at Islington in Christchurch that drives to the gateway, because on a Malvern lifestyle block or a transport yard nobody is bringing the gate to us. Sydney Chappell founded the New Zealand company in 2026. The company describes the history behind it 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.” The full range and the rest of our credentials sit on the page.
Before we drive out
Two things are worth doing before the visit, and both take five minutes. Pace out roughly how far the gateway is from the nearest power, because that number decides most of the supply conversation. Then stand at the gate, not at the house, and see how many bars your phone actually holds there.
Phone us on 027 424 0600 or email info@groupone.co.nz, 7am to 3pm Monday to Friday. Group One New Zealand, Unit 1, 37 Foremans Road, Islington, Christchurch 8042. NZBN 9429053752833.

Questions from Malvern gateways
Can a gate run entirely on solar out here?
Yes, and on a rural entrance it is often the sensible option. Panel and battery are sized to the daily cycles and the reserve you want through a dull winter week.
What does gate automation cost?
On quote. Solar or mains, the drive size the leaf demands, the number of credentials, retrofit or new build, and the run out to the site all move it.
How do I let a driver in when I am not on the property?
SIM-based remote release from your phone. Mobile or Bluetooth entry does the same where the driver is a regular.
