"We could well see gusts of 120, even 130km/h about exposed places," he said.
"We're quite hardy and we're used to strong winds in Wellington, but of course many of us last week enjoyed basking in the wonderful sunshine and the relatively calm conditions."
Wellingtonians that had invested in outdoor furniture or new trampolines over the Christmas period would have to tie them down or bring them in, he said.
"We've been enjoying all that outdoor furniture, but it is going to be very important to make sure it's well secured because it's going to be very, very windy."
"And also people putting out recycling, it's going to have to be very well secured to make sure it's protected from those strong northwesterly gusts."
He also advised motorists to take care on the roads in the windy conditions and watch out for fallen branches, especially those in high-sided vehicles or motorcycles.
While large swells were not expected through the Cook Strait he encouraged anyone with travel plans to check the ferry schedule and Wellington airport for updates.
