Cyclone Hola has been upgraded to a Category 4 cyclone, and experts are warning we could be hit as soon as Sunday.
The Fiji Meteorological Service upgraded the cyclone on Thursday morning as it moves across the Pacific - and say it is still intensifying.
"Current forecast tracks indicate the system will move westwards across Malakula, Vanuatu over the coming days, before recurving late Thursday - early Friday and heading southeastwards towards New Zealand waters," MetService says.
"Some of the models are indicating that it could pass by the upper North Island late Sunday into Monday. The position and timing of the recurve will determine the final track."
NIWA warns Hola is expected to strengthen even further on Thursday, becoming a 'Severe' Category Three cyclone.
Video shows the eye moving over Vanuatu, bringing with it devastating winds, heavy rains and rough seas.
It's not known exactly when Hola will be unleashed on New Zealand. Fortunately, weather forecasting site Weather Watch says it will likely weaken before hitting us.
"Late this week Hola is likely to track south and into less favourable conditions, allowing it weaken some as it drops towards the New Zealand area," it says.
"It's still quite uncertain where Hola will track in the New Zealand area though - we will need until Friday to be able to be more specific about this."
