Flood Room

Flood room is monitoring

Updated at 10.30am on Tuesday, 2 June 2026

Situation

MetService has cancelled most of the Heavy Rain Watches for the region. The Heavy Rain Watch for Taupō will likely be cancelled at 11am today and the Heavy Rain Warning for Bay of Plenty (including eastern catchments of the Waikato region) will likely be cancelled by 1pm today.

While the two heavy rain alerts still have some hours to expire, we do not expect much more rain for those areas.

Luckily, the downpours forecast by MetService didn’t eventuate, however it is always best to prepare for the worst and hope for the best. 

Flood Room will move to Deactivated at 1pm today.

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.

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. 

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.

Please keep up to date with the current MetService weather forecasts and messages from local Civil Defence.

Issued at 8.04am, Tuesday 2 June

Heavy Rain Warning (Orange) - Bay of Plenty and Rotorua about and west of Whakatane (includes eastern catchments of Waikato Region)

Period: 5 hours from 8am - 1pm Tuesday, 2 June
Forecast: On top of what has already fallen, expect 30 to 60 mm of rain. Peak rates of 10 to 20 mm/h expected, but 25 to 40 mm/h in possible localised downpours. Minimal chance of upgrading to a Red Warning.

Heavy Rain Watch - Taupō

Period: 3 hours from 8am – 11am Tuesday, 2 June
Forecast: Periods of heavy rain and amounts may approach warning criteria. Localised downpours possible Tuesday morning. Moderate chance of upgrading to a Warning.

Thunderstorms

There is a low risk of thunderstorms for Coromandel Peninsula until late evening. For Bay of Plenty from Tauranga westwards, Waikato, Waitomo, Taupō, Tongariro National Park, there is a low risk of thunderstorms this morning and afternoon, with a low risk of localised downpours this morning.

For information on preparing for and keeping safe during a storm, see the National Emergency Management Agency's Get Ready website.

Likely/potential Impacts

Catchments

There has been a massive amount of work undertaken by Waikato Regional Council operations teams in the severely impacted catchments of the Coromandel Peninsula, Waipā, Ōtorohanga and Waitomo areas. However, these areas are still recovering and may still be fragile if downpours occur in these areas.

Rivers and lakes

There is a possibility heavy rain may cause rivers and streams to rise rapidly. 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

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 deactivated at 1pm today (Tuesday, 2 June).
