Wayby Valley Landfill
To ensure our wider whānau are well informed, this page brings together key information about the Wayby Valley Landfill — what has happened so far, where things currently stand, and what lies ahead.
The kaupapa
The proposal to create a large-scale landfill in Wayby Valley – that sits within the rohe of Ngāti Manuhiri – has been under legal and environmental challenge for several years. Our three entities:
Te Rūnanga o Ngāti Whātua
Te Uri o Hau Settlement Trust
Ngā Maunga Whakahii o Kaipara Development Trust
have worked collectively to oppose the resource consent for the landfill over the past six years.
In May 2025, we made the difficult decision to withdraw opposition from the legal process.
We did not reach this decision lightly. It came after weighing up:
An independent peer-reviewed report that found the consent could not be declined on the grounds of leachate or environmental risk alone
The high and ongoing legal costs we would continue to face – especially if we lost
The limited influence remaining through litigation
