Reline NZ

Established in 2012, Reline NZ has fast become an industry leader in the delivery of trenchless pipeline rehabilitation solutions nationwide. Operating two internationally-recognised relining systems, we have the right technology and specialist technicians to provide safe, efficient, and cost-effective rehabilitation of aged and damaged pipelines.

Our services include project management, technical support, and consultancy services for the successful delivery of small and large scale rehabilitation projects.

What We Do

EX Lining

Reline NZ's EX lining system involves the expansion of a continuous coil of specially formulated PVC pipe to form a tight fitting liner within the existing host pipe.

EX linings are designed to deliver a stand-alone structural liner, providing the same strength and durability of a new PVC pipe without the need for excavation.


Reline NZ's innovative Alphaliner is a complete pipe rehabilitation system utilizing exciting, UV curing technology to its fullest potential. Pipeline sections rehabilitated with Alphaliner can expect a service life of approximately 50 years, allowing for a prolonged depreciation period.

Alphaliner UV curing technology is developed and produced by RELINE EUROPE, and has proven itself to be a secure and economic process, accounting for 70% of the European pipeline rehabilitation market.
