Situation
MetService has issued a Heavy Rain Warning for Coromandel Peninsula and the Bay of Plenty, which includes the eastern catchment of the Waikato region.
This is a convective system with potential thunderstorm and localised downpours. We have spoken to a severe weather forecaster at MetService and they brief that while the official Orange Warning is currently focused on these areas, this situation may escalate and other parts of our region may get affected. We will advise as MetService updates the forecast and the situation.
Our catchments are generally in a good condition with some capacity to ‘soak up’ some rain; however, high intensity downpours can cause high runoff, especially in steeper catchments.
While we are not expecting widespread flooding, we may see localised areas of surface flooding and land instability.
The Regional Flood Response team continues to monitor forecasts and flood and drainage infrastructure, and will liaise closely with civil defence, local councils and other agencies if circumstances change.
If an event does occur:
- Avoid driving through floodwaters and plan alternative routes if you live in a flood‑prone area.
- Contact local Civil Defence (or your council) if you observe any evidence of a landslip or flood impacts.
- Contact 111 if you are in immediate danger.
Be prepared
- Download the MetService App to your phone to receive severe weather alerts for your area.
- Add links to your local council and civil defence emergency management websites and follow their social media profiles.
- Check drains and gutters around your property to ensure water can flow freely.
- Secure outdoor items that could blow away or block drainage channels.
- Review your household emergency plan, including how you will stay informed if conditions change.
Please keep up to date with the current MetService weather forecasts and messages from local Civil Defence.

Thunderstorm outlook
Valid from midnight Tuesday, 23 June to noon Wednesday, 24 June
For the southwest of Northland and the majority of Auckland, far northern Waikato and also Coromandel Peninsula, the risk of thunderstorms is low as indicated on the chart.
Valid from noon Wednesday, 24 June to midnight Wednesday, 24 June
There is a moderate risk of thunderstorms and localised downpours for the far southeast of Northland, far northern Auckland, Great Barrier Island, Coromandel Peninsula and far western coastal Bay of Plenty during the afternoon, continuing in Coromandel Peninsula into the evening and spreading further east through coastal Bay of Plenty to about Whakatane from evening onwards. These thunderstorms may be accompanied by heavy rain of 10 to 25 mm/h, with downpours increasing rainfall rates to 25 to 40 mm/h in localised places. Localised downpours may occur with or without thunderstorms. There is also a moderate risk of thunderstorms for much of Northland during the afternoon as indicated on the chart, decreasing to low in the evening and becoming confined to the coast.
There is a low risk of thunderstorms and localised downpours for the majority of Auckland during the afternoon, for Waikato during the afternoon and evening and for inland Bay of Plenty and the far north of Taupō in the evening and at night.
However, there is always a possibility severe thunderstorm watches or warnings may be issued by MetService at short notice, so please be alert for and act on these without hesitation – do NOT wait for further analysis by Waikato Regional Council. For information on preparing for and keeping safe during a storm, see the National Emergency Management Agency's Get Ready website.
Likely/potential Impacts
Rivers and lakes
Our catchments are generally in a good condition with some capacity to ‘soak up’ some rain, however high intensity downpours can cause high runoff, especially in steeper catchments.
While we are not expecting widespread flooding, we may see localised areas of surface flooding and land instability.
If there has been recent rainfall, some streams and rivers may be above expected normal levels for 36-48 hours after the event. If an event does occur, avoid driving through floodwaters and plan alternative routes if you live in a flood‑prone area. Contact 111 if you are in immediate danger.
Wind
There are no Strong Wind Warnings or Watches issued for the Waikato region. However, downbursts and strong localised winds can occur with thunderstorm activity. Trees may fall and powerlines may come down (treat all as live). Any unsecured items may be uplifted, so now is a good time to tie them down or bring them inside. High-sided vehicles may be affected by strong winds.
Please keep up to date with information from your local power provider, the NZ Transport Agency Waka Kotahi and local civil defence.
Coastal impacts
No significant coastal impacts are expected.
Land instability
Many catchments across the region are still recovering following heavy rainfall this year. As a result, areas that would normally experience land instability may be affected by any localised downpours that develop about the hill country and ranges of the region. People in these areas should remain vigilant for early warning signs of earth movement. Road users should plan ahead and keep up to date with the latest from their local council and the NZ Transport Agency Waka Kotahi.
Contact local civil defence (or your council) if you observe any evidence of a landslip or flood impacts. Dial 111 if you are in immediate danger. Road users should plan ahead and keep up to date with the latest from their local council and the NZ Transport Agency Waka Kotahi.
Warning signs:
- Small slips, rock falls, and sinking land, at the bottom of slopes.
- Sticking doors and window frames, which may mean the land is slowly moving under the house.
- Gaps where window frames are not fitting properly.
- Steps, decks, and verandas, moving or tilting away from the rest of the house.
- New cracks or bulges on the ground, road, footpath, retaining walls and other hard surfaces.
- Tilting trees, retaining walls, or fences.
- Water flowing out of a slope, like a new spring.
If you learn or suspect that a landslide is occurring, or is about to occur in your area, here’s what to do:
- Move quickly out of its path and stay away from it. Evacuate immediately if it is safe to do so. Your best protection is higher ground outside the path of the landslide.
- If you cannot leave safely, the side of your house furthest from the landslide is likely to be the safest location on your property.
- Take your pets with you and move livestock to safe paddocks if you can do so without endangering yourself.
- Alert your neighbours. They may not be aware of the potential hazard. It may save their lives. Help neighbours who need assistance to evacuate if you can do so without putting yourself in danger.
What we're doing
Our Regional Flood Response team of scientists and subject matter experts continues to analyse the latest data and provide advice to civil defence, district and city councils, other partners, stakeholders and agencies. This data is received, analysed and updates are disseminated continuously, 24 hours a day.
Our local Flood Response teams monitor catchment impacts, operate flood and drainage schemes, and work with local stakeholders to respond to local issues.
Waikato Regional Council flood and drainage schemes
All flood and drainage infrastructure is working as it should. Local flood response staff continue to monitor forecasts and assets to ensure a timely response, should it be required.
Please note, drainage schemes will take time to return to the pre-event conditions following rainfall. Rest assured our local operations staff are monitoring.
Waikato Regional Council telemetry
Our telemetry network continues to provide real-time data on rainfall and river levels and is monitored 24/7 by our Regional Flood Response team. Visit our Environmental Data Hub for the latest river level and rainfall accumulations.
Next update
Flood Room will be updated by 1pm tomorrow (Wednesday, 24 June) or earlier if conditions change or further weather alerts impacting our region are issued.
