The following reports are relevant to our mahi (work) on the awa:

Te Mana o te Wai refers to the vital importance of water. When managing freshwater, it ensures the health and well-being of the water is protected and human health needs are provided for before enabling other uses of water. It expresses the special connection all New Zealanders have with freshwater. By protecting the health and well-being of our freshwater we protect the health and well-being of our people and environments. Through engagement and discussion, regional councils, communities and tangata whenua will determine how Te Mana o te Wai is applied locally in freshwater management.


Discover a cutting-edge study on plastic retention in estuaries, focusing on the Waitemata Estuary including Te Wai o Pareira. Advanced simulations reveal that over 60% of river-sourced buoyant plastics end up on the shore within ten days, challenging conventional beliefs. Explore how factors like tides, winds, and freshwater discharge influence this phenomenon and reshape our understanding of plastic behavior in estuaries.

This report, undertaken for Auckland Council by Tonkin and Taylor ​in 2018 covers a comprehensive review of the areas in Henderson (including Te Atatu Peninsula) for potential flooding.  The model  takes into account the effects of climate change and predicts a one in a hundred year flooding event to cause 234mm of rain in 24 hours.  The January 2023 floods were not far off this number at 240mm, although 291mm fell from 27th to the 31st January.

This paper discusses key steps in the consenting process and features of the consent, as well as the key lessons learnt.

This report details National's policy for freshwater management.

This report recommends that estuaries and the waterways that feed into them are treated ​as a single entity 'from the mountains to the sea'.

Auckland Council has a series of guidelines on how to minimise the impact of many common activities such as concrete waste, food waste, paint waste, vehicle and equipment washing and water blasting​.


Comment from Rivercare Group Te Wai o Pareira:  We are very hearted to read this feedback and to note that Watercare has acknowledged the high number of wastewater discharges that are occurring in Te Wai o Pareira.  However, we are very disappointed to see that significant change to this situation appears to be years, even decades away.  In addition, if the timing of Stage 1 of the Northern Interceptor is an indicator, this is very bad news.  Stage 1 of the project has been delayed 3 years over the date initially mentioned to us
