Authorities are urging whānau across the motu to prepare as Cyclone Vaianu is expected to move south across the North Island on Sunday, bringing a dangerous mix of wind, rain and coastal impacts.
MetService has upgraded Great Barrier Island and the Coromandel Peninsula to Red wind warnings, signalling the most severe level of alert as the system approaches.
The cyclone is being described as a multi-hazard event, with the potential to cause widespread disruption and danger. Forecast impacts include damaging winds, heavy rainfall, and coastal inundation, all of which could combine to create life-threatening conditions in some areas.
Emergency authorities are warning that the exact locations of the most severe impacts will depend on the cyclone’s final track. However, communities across large parts of the country are being told to prepare for:
- Power outages
- Falling trees and debris
- Flooding and slips
- Road closures
- Potential isolation of some communities
Strong wind and heavy rain watches and warnings are already in place for much of the North Island and the upper South Island, covering Sunday into early Monday.
Forecasters say additional regions could be escalated to Orange or Red warnings as the cyclone moves closer and its path becomes clearer.
Officials are encouraging people to take the situation seriously and prepare early, particularly in areas already under warning.
That includes:
- Securing loose items around homes
- Preparing emergency supplies such as food, water, and torches
- Checking travel plans and avoiding unnecessary movement
- Staying informed through official weather updates
With conditions expected to change rapidly, authorities stress the importance of keeping up to date with the latest forecasts and following guidance from Civil Defence and local councils.
Cyclone Vaianu arrives at a time when many communities are already dealing with weather-related challenges, increasing concern about the potential for cumulative impacts.
Emergency management teams are on standby, but the message is clear:
prepare now, stay informed, and be ready to act.
For many across the motu, Sunday could bring significant disruption – and for some, dangerous conditions – as Cyclone Vaianu makes its way across Aotearoa.
