Aucklanders are being warned to prepare for power cuts this weekend

MetService has issued a strong wind watch for the entire upper North Island.

Vector has rostered on additional response crews and storm management teams in preparation.

Head of Network Field Services Marko Simunac says some issues might take time to fix as it's unsafe for crews to work in high wind.

People are encouraged to keep a torch and spare batteries handy, tie down outdoor objects and turn off appliances at the wall if there's an outage.
