Background to the project: The Infrastructure Acceleration Fund (the Fund) is a key component of the Government’s $3.8 billion Housing Acceleration Fund announced in March 2021. The Fund is to enable housing development in areas of need throughout Aotearoa New Zealand through the allocation of funds to new and upgraded eligible “enabling” infrastructure such as transport, three waters and flood management infrastructure. The contestable fund available is at least $1 billion.

Queenstown Lakes District is one of the fastest growing in New Zealand and housing affordability is a significant issue. Hawea is identified as a growth area and the Longview development is unlocking affordable housing potential. Longview and future development are subject to the appropriate infrastructure being in place, as the existing Hawea wastewater system is inadequate.

Queenstown Lakes District Council was invited to take its Hawea Wastewater proposal through to the next phase of the funding application process.

The case:

QLDC sought consultancy services to further develop the compelling housing demand and infrastructure investment story and complete the IAF application required. Tregaskis Brown was selected to develop and deliver the:

  • comprehensive financial story to back the investment including co-funding elements
  • complete housing demand story
  • foundational engagement with tangata whenua to support the project
  • completed application with letters of support from tangata whenua and stakeholders, and other supporting material.

The outcomes:

“It is great to have a provider that can deliver a high-quality, comprehensive product that is right first time.” Jesse Taylor, Senior Investment Advisor, Queenstown Lakes District Council 

QLDC and Tregaskis Brown eagerly await what we hope is a positive outcome of the contestable fund process. Until a funding decision is made, expected later in 2022, we remain on call as trusted advisors to QLDC when questions arise during this time.

The project required a substantial amount of council and stakeholder collaboration and the timeframes for completion were tight. QLDC expressed that is unique for them to have providers that deliver a high-quality, comprehensive product that is right first time. As QLDC continues to tackle its growth and infrastructure challenges we look forward to working with them again.
