0 Main.jpg

Client: Kainga Ora

Project Value: $5.5m

Completion: early 2022

Project Type: Infrastructure
Our role:  Client Project Manager & Infrastructure Manager

As part of the Kainga Ora Northcote Development, Kainga Ora are replacing 300 existing state houses and delivering more than 1,500 warm, dry, quiet houses in their place.


In order to aid this growth and to prevent flooding in large storm events, the Stormwater network in the entire precinct required upgrade.


The Tonar Street SW Pipeline project involved the installation of a new 2.1m diameter  SW line 200m under the sports fields on the Hato Petera Grounds in Northcote.

The pipe was 7-8m underground and the outlet discharged into the Akoranga Reserve and Hillcrest Creek.


It was a complex project where the pipe was installed by Piritahi (Kainga Ora’s Alliance Delivery Partner) using a Tunnel Boring Machine, and required extensive negotiations and communications with the local stakeholders and owners of the land.

Safety was paramount through all aspects of delivery especially with the nature of the high risk works and working environment.


TOBA Projects provided Client-side Project Management and Infrastructure Management services to Kainga Ora from design, Alliance TOC (Target Outturn Cost) development, Resource Consent and EPA lodgement, and construction phases.
