Waikato residents received an Emergency Mobile Alert at 8.10pm on Friday after MetService issued a red severe thunderstorm warning in or near the region.

Civil Defence says heavy rain could cause rivers, streams and road surfaces to rise rapidly. People in low‑lying or flood‑prone areas are being told to take extra precautions and be prepared to evacuate quickly. If you see rising floodwater, ground movement, small slips, or tilting trees or buildings, evacuate immediately and do not wait for another warning.

Those who need to leave should seek shelter with friends or family if possible and take pets and essential items. People are asked to stay off the roads and avoid all non‑essential travel. Do not drive or walk through floodwater, which is dangerous and may be contaminated. Emergency services may be delayed; call 111 if life or property is at risk.

The alert was issued by the Waikato Civil Defence Emergency Management Group. Further updates and advice are available at waikatocivildefence.govt.nz.
