Pipeline Construction

Warner’s substantial pipeline construction capabilities are found in multiple work shops located in New Plymouth and Taupo. The premises include specialist facilities for modern Plasma Cutting machines, and Sub Arc Welding works. Warners pipeline capacity works is impressive; they have recently fabricated and installed a 15km (approx) pipeline at the Tauhara Steam Field in Taupo, in the Central North Island of New Zealand. Efficiency and reliability with world class safety standards have ensured Warners ongoing projects in the fast-paced and growing renewable energy sector to continue.

Geothermal

The majority of Warner Constructions Geothermal and Hydro works have historically been for Contact Energy and Mercury, however they will fabricate and install any engineering related projects anywhere in New Zealand.

Over the last decade Warner’s reliability and quality of works have enabled them to dominate key projects for the majority of geothermal pipeline works in Taupo and the greater Bay of Plenty region of New Zealand. Warner Construction have recently completed their largest pipeline project for Contact Energy - the Tauhara Steamfield, and warmly invite you to view their Geothermal projects portfolio.
