Weather forecasts and sites monitored

Published Thursday, 1 May 2025

Situation

A deep low pressure system lies about and east of central New Zealand today but has moved south away from the Waikato region. The western areas and Waihou Piako zones of our region received moderate rainfall over night.

Visit our Environmental Data Hub for the latest river level and rainfall accumulations.

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.

There are no Warnings or Watches for the Waikato region.

What we are now doing

Our response staff continue to monitor weather forecasts and key sites across the region.

Likely/potential Impacts

Rivers and lakes

We are monitoring the Waihou River, which takes some time to respond to the rainfall from the last 36 hours. As the water moves downstream, the river will begin to peak in areas like Tirohia.

Downstream of Paeroa, the Waihou River is influenced by coastal tides, so you can expect higher river levels during high tides.

The Waihou River in Te Aroha is still rising but we anticipate it will begin to recede later today.

Wind

There are no Warnings or Watches.

Please keep up to date with information from your local electricity provider for power outage extents and estimated restoration times. The latest roading conditions will be available from your local council and NZ Transport Agency Waka Kotahi.

Coastal impacts

The coastal conditions are now easing, coastal impacts are unlikely for the remainder of this weather event.

Land instability

As expected, several shallow landslides have occurred around the Coromandel Peninsula and impacted local roads.
While the main rainfall event may have passed 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 have received the highest rainfall so the Tapu-Coroglen Road and State Highways 25 and 25A in particular will remain vulnerable for a time. Travellers using these routes should check the latest road conditions with Thames-Coromandel District Council and NZ Transport Agency Waka Kotahi.
