Anzac long weekend weather 

Updated at 11.15am on Thursday, 24 April 2025

Situation

The region has so far enjoyed a settled week weather-wise, following a period of unsettled weather from Ex-Tropical Cyclone Tam over the Easter long weekend.

Eastern parts of the Waikato region experienced extreme rainfall last week, with most of the rain falling from Wednesday to Saturday. The highest rainfall accumulation rates were recorded at the Pinnacles and Golden Cross rainfall gauges, with overall rainfall accumulation being between a 10% and 20% AEP event (a 1-in-5 to 1-in-10 year Annual Return Interval rainfall event).

The outlook for the weekend and early next week indicates a low risk of heavy rain for northern parts of the region from Sunday through to Tuesday. Additionally, we are entering a period of king high tides over the next few days. For the latest weather forecast please visit the MetService website.

Due to this, Flood Room Live will remain in monitoring.

MetService forecast

Changes to the weather can occur quickly, so please keep up-to-date with the latest forecasts. For national severe weather information, MetService is New Zealand’s only authorised provider of Severe Weather Alerts.

No Watches or Warnings are in place for rainfall, thunderstorms or wind. However, there is a low risk of heavy rain for northern parts of the region, including the Coromandel Peninsula, from Sunday through to Tuesday next week. 

What we are now doing 

All rivers across the region have either receded to before event levels or are continuing to recede. Our response staff will continue to monitor key sites across these areas over the coming days. 

Likely/potential Impacts

Rivers and lakes

While all rivers across the region have either receded to pre-event levels or are continue to recede, any further rainfall may cause rivers and streams to rise again. Our response staff will continue to monitor. 

Coastal impacts

We are moving into king high tides this weekend, with the highest tides expected from 27-30 April across the region. We will monitor for any possible coastal impacts during this time.  

Land instability

While the main rainfall event may have passed, with any further downpours it is important to be aware of a heightened landslide risk in coming days as soils are more saturated.

Central and southern areas of the Coromandel Peninsula received the highest rainfall, so the Tapu-Coroglen Road and State Highways 25 and 25A in particular will remain vulnerable for a time. Additionally, high country on the west coast and southern parts of the region may be vulnerable to slips.

Travellers in these areas should check the latest road conditions with their local council and NZ Transport Agency Waka Kotahi. 

Waikato Regional Council flood and drainage schemes 

All Waikato Regional Council-managed flood infrastructure is operating as expected. 

Our local operations staff will continue to monitor our flood and drainage schemes.

Please note, drainage schemes will take time to return to pre-event conditions. Rest assured our local operations staff are monitoring.

Waikato Regional Council telemetry

All Waikato Regional Council telemetry is working. Visit our Environmental Data Hub for the latest river level and rainfall volumes. 

Next update

The outlook for the weekend and early next week indicates a low risk of heavy rain for northern parts of the region from Sunday through to Tuesday.

Flood Room Live will be updated before 1pm on Saturday, 26 April, or sooner if needed.
