Aucklanders are being warned high winds and could cause power cuts overnight, while the central North Island could be hit with heavy snow falls over the same period.
Metservice had advised winds could gust up to 110km/h this evening and overnight, until around 8am on Saturday.
A release from Vector said these gusty winds had the potential to damage power lines either directly or indirectly if trees or debris were to knock them down.
There was a higher-than-usual chance of power cuts as a result of this.
Vector Chief Networks Officer Andre Botha said Vector was preparing response teams in the case any power outages occurred.
