Tiger Tail Power Line Sleeving in Auckland

OVERHEAD LINE SAFETY

When You Need Tiger Tails

Most overhead power lines in Auckland are bare conductors. Not insulated. Not shrouded in plastic like the cables inside your walls. The line running past the corner of your roof, across the back of the section, along the fence line, it is live and unshielded.

The legal trigger is 4 metres. If any part of your work, people, tools, equipment, or materials, will come within that distance of an overhead live line, you need a written close approach consent from the property owner, a separate consent from the relevant lines company, and tiger tails installed by a qualified electrician before anyone starts.

The jobs that most commonly put Auckland tradies in this situation:

• Roofing repairs or replacement where the service line crosses close to the eaves
• Scaffolding erection for multi-story renovation or exterior painting
• Building extensions, second-storey additions, deck or pergola construction
• Concrete pours using truck-mounted boom pumps (the boom sweeps a wide arc)
• Swimming pool excavation and surround construction
• Tree removal or trimming near property boundaries
• Fence installation when tall posts or materials approach the line
• Drainage work and underground services when plant tracks near poles

What We Handle

Site assessment first. TAE visits the property, confirms where the overhead line runs, measures actual working distances from your planned work zone, and determines the line voltage. Different voltages carry different clearance rules under NZECP 34 (the New Zealand Electrical Code of Practice for Electrical Safe Distances). We need the right information before any consent paperwork goes in.

Then the Close Approach Consent Form. This is the WorkSafe-recommended document that makes your work legal. Three sections: we complete the work description and proposed control measures; a competent electrician with a current EWRB practising licence certifies the plan meets NZECP 34 requirements; the property owner signs off. TAE manages sections one and two and tells the property owner exactly what they are signing.

Lines company notification runs at the same time. Central Auckland sits on the Vector network; wider Auckland areas fall under Orion Group. Both require written consent and a minimum of two full working days notice before work begins. TAE contacts them directly and chases written confirmation. You do not have to navigate their systems.

Installation by a licensed electrician. Tiger tails are clipped over the live conductor from one end of your work zone to the other, plus a minimum of 2 metres past each end. Bright yellow and black, visible from anywhere on site. Under New Zealand regulations, installation must be carried out by or under the direct supervision of an EWRB-registered electrician (EWRB is the Electrical Workers Registration Board, which licences all sparkies in New Zealand). Not a builder. Not a labourer.

They stay in place for the duration. Daily visual checks before work begins are required throughout the project to confirm the sleeves are secure and undamaged. If something shifts overnight, work stops until it is back in position.

Removal and documentation on completion. When your job is done, TAE removes the sleeves and the site goes back to how it was. All consent forms, certification, and installation records are provided for your compliance file.

WHERE WE WORK

Tiger Tail Sleeving Across Auckland

Auckland is dense. Overhead power lines run through established suburbs at roof height, across narrow lots, alongside scaffolding that has no choice but to go up close to them.

TAE installs tiger tails across the Auckland region, from the Vector-served central suburbs to the Orion Group-covered outer areas. Different lines companies have slightly different consent processes. We deal with both regularly and know what each one needs to turn around approvals without delay.

The jobs we see most: roofers in Remuera and Mt Eden where the service line drops almost to eave height. Scaffolding contractors in Ponsonby and Freemans Bay working on villa renovation where the scaffold frame ends up inside the 4-metre zone. Builders in Manukau and Pukekohe adding extensions to homes with lines running across the back yard.

WorkSafe NZ’s guidance on working near low-voltage overhead electric lines makes clear that enforcement is active and the consequences of getting this wrong are significant. Recent Auckland prosecutions have included fatal electrocutions and, in one documented case, a scaffolder who lost both arms to a live overhead line after consent requirements were not properly communicated to the crew on site. The line did not move. The paperwork was not followed. That is the risk.

Not sure whether your job triggers the requirement? Call us. The site visit answers that question before anyone lifts a tool.

THE PROCESS

What to Expect

WHY TAE

Why Choose Totally Amped Electrical

Tiger tail installation looks straightforward on paper. What makes it go wrong is the paperwork, and the people who skip it.

The Close Approach Consent Form requires a competent electrical worker with a current EWRB practising licence to certify the proposed control measures in writing. That cannot be filled in by the builder, signed off by an unlicensed tradesperson, or backdated after work has already started. Every TAE electrician holds a current practising licence. The certification is legitimate and your project is compliant from the moment your crew arrives on site.

We also know Auckland’s lines companies. Vector’s close approach consent process has specific online submission requirements. Orion Group’s process is slightly different. We deal with both regularly, so approvals come back without unnecessary delays.

The turnaround is fast. A site assessment, consent coordination, and installation can generally be arranged within a few working days of your call, meaning tiger tail installation can run alongside your other pre-start prep rather than becoming its own hold point on the programme.

Is tiger tail installation a legal requirement in New Zealand, or just recommended practice?

Legal requirement. NZECP 34 is a binding code of practice under the Electricity Act 1992 and the Health and Safety at Work Act 2015. It requires documented control measures before work proceeds within 4 metres of an overhead live line. Tiger tails are one of the accepted control measures. WorkSafe NZ enforces NZECP 34 and prosecutes non-compliance. Penalties under the HSWA run up to $300,000 for individuals and $3 million for companies. It is not optional.

Who is actually allowed to install tiger tails in New Zealand?

Installation must be carried out by, or under the direct supervision of, a competent electrical worker holding a current practising licence from the EWRB. A builder, roofer, or scaffolder cannot legally install them. This is why the Close Approach Consent Form requires a licensed electrician to certify the control measures before the property owner signs, the licensed electrician is taking professional responsibility for the plan.

Do tiger tails fully insulate the power line? Can our crew brush against them?

No. Tiger tails reduce the severity of accidental contact but they do not make the line safe to touch. WorkSafe is explicit about this. They are a visual marker and a partial protective barrier, not a guarantee. Minimum approach distances still apply even with tiger tails in place. Anyone who says the line is covered so it is fine is wrong.

How much notice does the lines company actually need?

Two full working days minimum, in writing, before work starts near the line. That applies to both Vector and Orion Group. You must receive written confirmation before work can legally begin, not a verbal agreement. TAE contacts the lines company as part of our standard process. You do not have to manage that step.

What happens if the work needs to go closer than 0.5 metres to the line?

Tiger tails no longer apply. For any work planned within 0.5 metres of an overhead live line, the electricity supply to the property must be fully isolated before work starts. That means contacting your electricity retailer to arrange a disconnection. The supply stays off for the duration of the work. Tiger tails are only applicable in the zone between 0.5 metres and 4 metres from the conductor.
