ER117 The demographics and drivers of intensification in Greater Christchurch Stage two (August 2025)

Aotearoa New Zealand households are constantly evolving. The number of people living in a dwelling, the types of homes we live in and the number of cars for each household have shifted significantly over the past decade. The government’s National Policy Statement on Urban Development issued in May 2022 aims to encourage denser housing in areas of high demand and access. This has received mixed responses from communities and councils across Aotearoa New Zealand. For instance, Christchurch City Council is looking to deliver a bespoke solution, with an independent investigator appointed to work with the council on its housing intensification plan.

Using Ōtautahi Greater Christchurch as a case study, this research aims to improve our understanding of the changing needs in this region and how they are affecting the demand for housing. It aims to inform the debate around housing intensification and provide a platform that can be replicated in other housing markets.

Using Census data and interviews with stakeholders and residents, the research includes analysis of changes in households, their different dwelling typologies and vehicle ownership. It also investigates the constraints of the housing system.

The researchers will also deliver in-depth seminars at the end of each stage focused on making the findings accessible for council, government representatives and other key stakeholders.

With improved understanding of the interaction between population growth demographics and housing demand by location, type and tenure, we can better predict and prepare for housing market needs of the future.
