Porirua, in New Zealand’s Wellington Region, is growing fast, with another 29 000 people expected to be living in the area within the next 30 years. The city will need to provide 11 000 quality homes to support its expanding community.
In November 2018, the NZ Government announced a NZD 1.5 billion investment over the next 25 years to work with the community on revitalising Porirua’s eastern suburbs.
Kāinga Ora – Homes and Communities, the Crown Entity responsible for housing and urban development, is partnering with Porirua City Council (PCC) and Ngāti Toa Rangātira to deliver the Eastern Porirua Regeneration Project (the Project), which will provide 2000 new or renewed public homes and 1500 affordable and market homes. Through social procurement and public investment, the project aims to stimulate economic activity, create employment opportunities and improve well-being in Porirua.
Following our previous work with Kāinga Ora, Aurecon was commissioned to provide infrastructure master planning (waste, potable and stormwater; services; roads; geotechnical and traffic engineering) services to support the investment decisions and approvals required to kickstart the project.
Our team was tasked with assessing the state of the existing infrastructure and making recommendations on the investment required to support the project. This involved modelling various development scenarios, exploring staging options and providing high-level cost estimates. In addition, Aurecon was involved in supporting resource consent applications for early stages.
Aurecon worked closely with key stakeholders (PCC, Wellington Water, Waka Kotahi NZ Transport Agency, Greater Wellington Regional Council, Wellington Electricity, and Chorus telecommunications) to develop cost-effective, innovative infrastructure solutions to support the project.
Each stakeholder had different aspirations for the project, so Aurecon had to work carefully to align the different groups. Aurecon developed a suggested framework for the fair allocation of costs for consideration. We also developed a GIS web-based portal, which enabled all stakeholders to easily access project-related material, helping facilitate decision-making. With our people fully embedded within the design team, we were able to effectively challenge the technical solutions proposed and drive value for money.
One of Kāinga Ora’s key drivers is to enable Māori and Pacific aspirations for urban development in Porirua. Aurecon has worked closely with Kāinga Ora to engage meaningfully with these groups and the wider community, addressing their concerns and ensuring everybody gains from the project.
It’s important that the new homes are well-connected to jobs, transport options and community spaces. Aurecon led the traffic assessment for the project, exploring the best options for walking, cycling, public transport, and vehicles. This required extensive collaboration with traffic modelling and urban design subconsultants, as well as engagement with PCC, Greater Wellington Regional Council, and Waka Kotahi. Our work has considered both operational and capital improvement opportunities, with an emphasis on enabling connectivity and encouraging active and sustainable modes (cycling, walking, public transport).
Aurecon leveraged its technical expertise, local knowledge, digital analysis and advisory services to provide Kāinga Ora with a clear picture of the investment needed to realise the project, including infrastructure upgrades, renewals and cost.
This has provided Kāinga Ora with the certainty they need to secure funding and begin their work on regenerating and revitalising Eastern Porirua.
