Pipe Technologies Ltd

PipeTech. New Zealand owned and operated since 2003.

We rebuild pipes from the inside. No digging, no open trench, no torn-up road. The old pipe stays in the ground. A new one forms inside it. The street above stays exactly as it was.

From day one we saw a smarter, cleaner way to fix ageing underground infrastructure. Traditional dig-and-replace is slow, expensive, and hard on the community. Trenchless relining does the same job for a fraction of the cost, in a fraction of the time, with a fraction of the mess.

Grown out of Taranaki, trusted across New Zealand.

PipeTech started in our home region, relining pipes for New Plymouth District Council, South Taranaki District Council, and Stratford District Council. More than 20 years on, those relationships still stand. That says more about how we work than any sales pitch could.

We began as a CIPP patch installer. Fix the fault, move on. Over time we grew our capability, brought in better products, and built out a full range of trenchless lining systems. Today we run one of the most capable trenchless operations in the country.

Our lining systems.

We’re not tied to one product. We match the right method to your pipe, your ground conditions, and your budget. That’s the advantage of running a full suite of trenchless systems under one roof.

ASOE uPVC fold-and-form lining. A true trenchless structural liner. A folded PVC profile is drawn through the host pipe, then reformed with heat and pressure to fit the existing bore. The result is a smooth, jointless, fully structural new pipe inside the old one. No excavation. No resin odour. No long cure times.

ASOE FFRP (Flexible Fabric Reinforced Pipe). A flexible, fabric-reinforced liner built for pressure pipelines and pipes with bends or changing diameters. Where a rigid liner struggles, FFRP flexes to fit and still delivers full structural strength.

NUFLOW CIPP. As a licensed NUFLOW installer, we deliver cured-in-place pipe lining for laterals and mains from 100 to 225mm, including inversion lining and spot patching. CIPP handles the junctions and awkward runs other liners won’t reach.

UV CIPP for small diameter pipelines. UV-cured lining for smaller pipes. A light train cures the liner in place fast and under tight quality control. Quicker cures, less downtime, and a clean structural result in the pipes that need the most care.

Panel Lok. A mechanical panel lining system for large diameter and non-circular structures, culverts, and man-entry sewers. Interlocking panels build a new structural lining inside the old asset without ever taking it out of the ground.

One job, every time: a new pipe, installed without the dig.

Why trenchless. Why it matters to you.

Less time on site. A reline that would take weeks to dig and replace is often done in days.

Lower cost to ratepayers. Trenchless comes in well below excavate-and-replace, and you skip the road reinstatement bill entirely.

Fewer disruptions. No road closures dragging on. No detours. No weeks of noise and dust for the people who live there.
Fewer hazards. Less open excavation means less risk to the public, to traffic, and to our crew.

Longer asset life. A correctly installed liner adds 50 to 100 years to the life of the pipe. You get a near-new asset out of the one you already own.

Lower carbon. No spoil to cart away. No new pipe to manufacture and freight. No road to rebuild.

How we work.

Within PipeTech we push humility, perseverance, and determination. We’d rather build a relationship that lasts than chase the margin on a single job. Integrity and reliability aren’t line items on a website. They’re the reason councils keep calling us back.

Trenchless is a niche market in New Zealand. We’ve chosen to be very good at it rather than spread thin across everything. When you bring us a pipe, you get a team that does this, and only this, every day.

Proven, and recognised.

In 2023 PipeTech was named the leading trenchless pipeline rehabilitation provider in New Zealand at the BUILD Construction and Engineering Awards. Nice on the wall. The work speaks louder.

Built for what’s coming.

New Zealand’s three waters networks are ageing, and the bill to fix them is huge. Dig-and-replace alone can’t move fast enough or cheaply enough to close the gap. Trenchless relining is how councils stretch budgets, extend asset life, and keep water moving without tearing up every street to do it.

That’s the work we’ve been doing for over 20 years. That’s the work we’re built for.
