Tūwharetoa lifts rāhui on parts of Lake Taupō and upper Waikato Awa following wastewater spill
Tūwharetoa Māori Trust Board (the Trust Board) has lifted a rāhui it imposed six weeks ago on parts of Lake Taupō and
the upper Waikato Awa (river) following the collapse of a wastewater pipe that resulted in an estimated 800,000 litres
of wastewater spilling into the lake.
The rāhui was imposed on 5 July, following the wastewater spill on 2 July, to ensure the community was kept safe and the
areas affected by the spill (Tapuaeharuru Bay and the Waikato Awa to Aratiatia) had an opportunity to rest and recover.
Trust Board Chief Executive Topia Rameka says when the spill occurred, one of the first priorities was to put in place
an environmental and cultural monitoring plan, driven by Tūwharetoa mātauranga (knowledge), that would inform kaitiaki
(guardians) about the state of the moana (lake) and awa.
“Over these past six weeks, we have worked alongside our marae representatives to oversee the infrastructure remediation
work,” says Mr Rameka.
“We have also been busy implementing our monitoring plan which pulls together cultural data, water sampling, sediment
sampling from the shore and lakebed, and mahinga kai sampling”.
Mr Rameka says that following a thorough analysis of all the data, the Trust Board is pleased to report that
Tapuaeharuru Bay has returned to normal – kua ea.
“As a result, a karakia was undertaken yesterday and the rāhui over the bay has been lifted – kua whakawatea.
“The restriction over the immediate construction site remains in place until the final remediation work has been
“At the outset, we were clear that our moana and awa are very resilient and in time would heal themselves.
“We are so pleased with this outcome and wish to acknowledge our marae and kaumātua for their leadership during this
Mr Rameka says lifting of the rāhui does not signal the end of the Trust Board’s work on the matter, rather efforts will
now be focused on understanding why the incident occurred.
“This was a significant event for our community and it’s important that we take the time to understand what took place
in the lead up and take every measure to ensure it does not happen again.”
