Infrastructure upgrades key to unlocking land for housing

Most of Auckland’s infrastructure was constructed before the intensification Auckland is experiencing had even been considered. Fast-forward several decades, we have a city with an infrastructure network that wasn't designed for today’s population, let alone higher density. Piritahi is playing a vital part in solving these constraints to unlock Auckland’s housing provision. Engineers Ben Chester and Nigel Tse tell us more about what this involves.

Even without intensification, analysis of Auckland’s infrastructure shows that much of it is already struggling to cope. Over 100 years old in some areas, upgrades are underway to service the city into the future.

Modern standards require robust infrastructure to cope with severe weather events and climate change. In some parts of Auckland, the infrastructure required as part of these standards doesn’t even exist yet. For instance, the lack of a dedicated stormwater network in some of the neighbourhoods Piritahi is working.

When Ben and Nigel talk infrastructure they’re talking water supply, wastewater, stormwater, roading, power and communications. Basically, the stuff that’s out of sight and out of mind (until water doesn’t come out of the tap or the lights don’t turn on!). They investigate and design the bulk infrastructure required to service the areas chosen by Kāinga Ora - Homes and Communities for development into the future, and provide technical input to support Piritahi’s land development teams.

With the increase in population that comes with the increase of quality homes, the landscape of Auckland is changing and the infrastructure underground will need to change with it. “Higher demand on utility and transport infrastructure will be generated, and it all needs to go somewhere! Providing new and upgraded infrastructure is key to unlocking land for the housing that this city needs” says Nigel.

Untying knots and working through these complexities will enable Piritahi to lay the groundwork at scale and pace. As NZ’s first land development alliance, it's challenging the status quo and helping to equip the city to support a growing population.
