Copper thieves are cutting Auckland fibre: plan for a dead line

What police reported this week

On 6 November, RNZ reported that Auckland police are worried about rising copper theft from telecommunications infrastructure. Detective Sergeant Luke Blignaut told RNZ that thieves are going after old landline and internet cables that fibre has largely replaced. Fibre often runs alongside that old copper, so the thieves cut the fibre too. One recent cut to a fibre cable took service from an estimated 10,000 people in Swanson and Massey.

1News reported the same day that more than 3,100 homes and businesses across West Auckland lost internet after a fibre cable was damaged. 1News also reported that police arrested two men, aged 24 and 34, in Massey after they allegedly pulled wiring and equipment from a power box. Stealing telecommunications or power assets carries a maximum penalty of seven years in prison.

For business owners, the most telling detail comes from a Swanson school. Its internet lines were cut while staff were dealing with a medical emergency involving a student. Staff couldn't get the student's information from the school's online system, so they had to retrieve it manually from local servers. Police said the school's response was delayed by about 20 minutes (1News; Infrastructure News, republishing RNZ).

West Auckland has been here before

The area has already had a run of cable damage this year. On 21 February, about 8,000 households with fibre in Te Atatū, Henderson and Massey lost service from about 5.30am after several copper and fibre cables were damaged. Chorus didn't expect to reconnect them until the following day, according to the NZ Herald. In August, a Henderson Valley family on copper broadband went without a connection for about a week. Chorus told the Herald that the area had a history of network vandalism.

Very few customers still use the copper network. Chorus had about 44,000 copper services left at 30 June 2026, and fewer than 1,000 of those were inside fibre areas, according to a summary of its Q4 FY26 connections update. The cables themselves are still there, though. Disused copper sits in the ground beside live fibre, and its scrap value gives thieves a reason to dig. Police told RNZ that copper theft has mostly targeted homes and other residential property until now, but incidents involving telecommunications infrastructure are increasing. The arrests and the police warning to scrap metal dealers may slow the thefts. Neither will remove the copper lying next to working fibre, so West Auckland businesses should assume more cuts are possible.

What a cut fibre line does to a cloud-based business

Over the past decade, many NZ organisations have moved accounting, ERP, job management, phones, payments and file storage off the server in the back room and into cloud services. Hosting those systems with a large provider makes them more resilient at the provider's end. The weak point is now the single fibre line into each site. When that line is cut, every cloud system becomes unreachable at once, and the provider's own uptime record doesn't help the people sitting in the building.

The Swanson school's experience shows how a fallback works under pressure. The school did keep local copies of its records, and those copies let staff find what they needed. Getting to them still took around 20 minutes, which suggests the offline route wasn't something staff used routinely. A business that keeps no local copy of critical information would have nothing to reach during a cut. A business with an untested fallback should expect delays like the school's.

Phones are the second gap. Many firms have replaced landlines with cloud phone systems that run over the same fibre connection. When the fibre goes, customers' calls stop reaching the business and desk phones can't call 111. The Henderson Valley family ran into the same problem at home: poor mobile reception in the valley meant they relied on Wi-Fi calling, so every broadband outage also cut off their phone (NZ Herald).

Practical next steps

A business can't guard the cabinet on its street. It can control how long a cut line stops work, and the measures below suit any site that relies on cloud systems.

• Add automatic mobile failover at sites that can't stop trading. A 4G or 5G router can take over when the fibre drops. Where coverage allows, use a different mobile provider from your fibre retailer. Test the switchover by unplugging the fibre during a quiet hour.
• Ask your telco about separate network paths. Ask whether the mobile sites serving your premises connect back to the network along a different route from your fibre. Telcos don't publish which mobile sites share routes with damaged cables, so you'll need to ask directly.
• List what staff need in the first hour of an outage. Emergency contacts, health and safety records, today's jobs, bookings and key supplier numbers should be available offline on a device that doesn't rely on the building's connection. Refresh those copies on a set schedule.
• Check how your phones behave without internet. Set your cloud phone system to divert calls to mobiles automatically when desk phones go offline. Make sure staff know to use a mobile for 111.
• Write a short outage runbook and rehearse it once. The runbook should name who declares the outage, who calls the provider, how the business takes payments and how staff and customers hear about it. If your service desk follows ITIL 4, record connectivity loss as a known major incident with a tested procedure. Log every outage with its duration and cause.
• Read the fault terms in your fibre plan. Check whether the plan includes a restoration target. If your site can't trade offline and the plan has no target, price a business-grade service that has one, or a second fixed connection over a physically separate route if one is available.

Cloud migration budgets usually cover software, data migration and training, and treat site connectivity as a given. The West Auckland cuts show what happens when that assumption fails. We treat connectivity, offline fallbacks and phone failover as part of the digital transformation design for any cloud move. Businesses that have already moved to the cloud can do most of the steps above within a month, starting with the failover test.
