Judith Stanway to head flood review panel
An indepedent panel reviewing of the April floods in Rotorua is being chaired by Judith Stanaway, the Rotorua Lakes Council has announced.
The statement says Mrs Stanway, the former head of BDO Accountants and director of various bodies in Rotorua, will chair the independent panel which will review what happened and what contributed to flooding in Ngongotaha on 29 April and make recommendations for future mitigations.
The other panel members are Te Ururoa Flavell, Rob van Voorthuysen and Kyle Christensen.
The statement says the joint Rotorua Lakes Council and Bay of Plenty Regional Council review aims to learn from what happened and contributed to the flooding to improve the ability of the two councils to mitigate against, and minimise the impact of, adverse weather events.
Rotorua Mayor Steve Chadwick says she is pleased the panel is now in place and beginning its work.
“It’s very important to us that we learn from what happened, particularly given the increased frequency of adverse weather events and the understandable concern of our community about that.”
While the review will focus on Ngongotaha, the statement says it is expected to highlight areas where it can be applied across the district.
“We expect the recommendations that come out of this review will inform future infrastructure needs and help guide future decision-making,” Chadwick says.
The statement addes that the terms of reference agreed by the two councils note that current practice is for stormwater infrastructure to be designed to cope with a one-in-50 year event and for water courses within stop-banked urban river scheme areas to be designed to cope with a one in 100 year event.
“While this has been seen as a prudent approach in the past, climate change and the advent of more frequent extreme weather events raised a question as to the ongoing acceptability of this policy in the future. This is a serious issue and one which could have far reaching consequences for all Rotorua residents,” the Terms of Reference note.
“I commend the two councils for taking this step,” Mrs Stanway says. “It’s important people understand this this isn’t about blame but about looking forward. Our job is to understand the event and make recommendations for the future.
“The review is now underway - we’ve had an initial meeting and we are planning meetings with expert engineers and with some of the affected residents. We’ll also be looking to organise a drop-in session in Ngongotaha.”
The terms of reference were worked through and agreed by the chief executives of the two councils and are available on the Rotorua Lakes Council website.
The panel will consider regional and district planning matters, engineering options, stormwater, catchment management, future land use and subdivision development considerations and mātauranga Māori (Māori knowledge).
The cost of the review will be shared between the two councils.

Review Terms of Reference
Ngongotaha Flood Event
An unprecedented level of rainfall (165 millimetres: 1.5 times the April normal in 36 hours) during
the weekend 28-29 April 2018 caused the Ngongotaha Stream to overflow its banks causing
widespread flooding in the Western Road area. Inundation of the sewerage system further
exacerbated the situation through the direct contamination of flood waters.
