Water tanks


Built to last, in tough NZ conditions, our tanks are preferred by the experts because they stand the test of time. But we don’t just do good tanks – we know where they go and can provide expert water solutions.

Benefits of water tanks


Proudly designed and made in New Zealand from UV stabilized, food grade polyethylene compliant to the highest standard AS/NZS4766 with a 20-year warranty


Engineered tapered wall design, meaning strength where it is needed. Fittings up to 100mm can be directly installed to the wall, including compliant fire-fighting kits. Sand blasted non reflective finish in a range of six colours that blend in with the surrounding environment


Rural specialists know what good looks like, This is why they specify RXP – the tank they can rely on. Six lifting or tie down lugs make moving and securing simple and four flat panels makes fitting accessories and the installation of tank simple and easy
