Our vision at Piritahi is to change the way people live. We can do this by streamlining land development, laying the groundwork for neighbourhoods that are better to live in and homes that are more affordable.

Piritahi is an alliance of companies formed to speed up the supply of build-ready land. We prepare government-owned land for development and deliver new and upgraded infrastructure and amenity on behalf of Kāinga Ora – Homes and Communities. We are working within Kāinga Ora’s large-scale urban development areas where state-owned land is being better utilised for new warm, dry, healthy homes.

Our responsibilities include pre-construction and delivery of programmes of work that include; the removal of old state houses no longer fit for purpose; land remediation; arranging consents related to earthworks and infrastructure; construction of roads, parks and utilities, and looking after the communities we’re working in as we go. We also have several focus areas spanning our scope of work, meaning we collaborate to create outcomes that are far from business as usual! Work for Piritahi and be part of the core team of people developing a practical solution to Auckland’s housing challenges.

With projects spanning multiple urban environments across Auckland, and an up-to 5-year programme of work, this is a rare opportunity to be part of an alliance that will have a lasting impact upon the city’s communities. Surrounded by industry experts from six different companies all with a common purpose, a career at Piritahi is lined with incredible development opportunities.

The 3 Waters Team provide technical expertise in the areas of modelling, design and implementation of water and wastewater networks to support land development projects in largely brownfield catchments across the Auckland Housing Programme. We are looking to expand the team with appropriately qualified senior engineers/modellers.

The Senior Engineers will have a particular focus on water supply and wastewater modelling and will report to the Discipline Lead for the 3 Waters Team within the Piritahi Alliance.
