9 Sept 2026: El Niño preparations

Media: Rotorua Daily Post

Topic: El Niño preparations

Enquiry

I am looking into how the upcoming El Niño event may affect Rotorua and what Rotorua Lakes Council is doing in preparation.

Please see my questions below

• What are the main risks El Niño poses for Rotorua? Are any parts of Rotorua more vulnerable to El Niño conditions?
• What modelling or forecasts is the council using to prepare for the coming months?
• What steps has the council already taken to prepare for El Niño conditions?
• Have any changes been made to water management, parks maintenance, stormwater systems, or emergency planning?
• Is the council reviewing contingency plans for potential water restrictions?
• Are there any infrastructure projects or resilience measures that could help reduce the effects of prolonged dry weather?

Response

We suggested the reporter also speak with the BOP Regional Council, FENZ, Federated Farmers and forestry industry representatives and provided the following from Council:

From Group Manager – Infrastructure and Assets, Stavros Michael:

Rotorua Lakes Council is preparing for the drier conditions that can come with El Niño through its existing water conservation strategy, drought management plans and ongoing infrastructure planning. These plans are reviewed regularly ahead of summer, when water demand typically increases.

Council is also stepping up seasonal water conservation messaging to encourage practical steps the community can take to reduce unnecessary water use.

We understand Bay of Plenty has been identified as one the regions facing an increased wildfire risk this season due to dry conditions and local topography. As a result, we are particularly vigilant in monitoring the Redwoods and other high-risk areas.

We will continue working with Fire and Emergency New Zealand's Bay of Plenty District to share information and support readiness activities ahead of the summer season.

While Rotorua water sources are generally resilient in the short term, prolonged dry weather and higher demand can place pressure on water supply infrastructure including pumps and storage. Extended dry periods can also affect isolated rural, lakeside and marae communities, primary industries and increase the risk of wildfires.

Council will continue to closely monitor water use, source availability and weather patterns. Our drought management plans enable a staged response if required, ranging from public education and water conservation advice through to water restrictions.

Council has invested, and continues to invest, in projects that strengthen the resilience of the water network. These include additional reservoir storage, upgrades to critical water mains, connections between treatment plants, and a planned new pump station to help supplement supply in eastern Rotorua.

The community also has an important role to play by staying informed, following Council advice and avoiding unnecessary water use. Residents can also help by understanding local risks and ensuring their households are prepared for dry conditions, particularly during the summer months.
