The extent to which Auckland will be affected by Cyclone Evan cannot yet be predicted, the MetService has said.
The cyclone, which has caused havoc in the Pacific Islands, was upgraded from a category three to a category four storm on Sunday with winds of up to 270kmh battering Fiji yesterday.
It is currently on track to reach Northland and Auckland by the end of the weekend, just days before Christmas.
The MetService said it could bring some wet, windy weather to New Zealand over the weekend but the exact forecast was too uncertain to predict.
"It is forecast to track southwards. But there is a lot of uncertainty about how the track might evolve," MetService forecaster John Law said.
Fuelled by warm, moist atmospheric conditions, as the cyclone heads towards New Zealand its path and intensity will be dictated by the temperature of water it crosses and the weather systems it encounters.
"There are lots of factors that define the path which make it hard to predict. There is such a spread of possibilities, to give any clear concise answer is very difficult," Law said.
Kiwis should monitor the cyclone as it is approaches the North Island throughout the week and forecasts become more accurate, he said.
"It is a forecast I would keep aware of, but it is a forecast that is still some way off. Be aware and keep checking."
