Wellington's music festival Homegrown is a casualty of the wild weather battering parts of the country today.

It was due to begin this afternoon to a sold-out crowd.

But organiser Kelly Wright says a decision has been made not to put people at risk, with over a 100 kilometre an hour wind gusts forecast today.

"We have decided to postpone the festival date. It'll be postponed until tomorrow where it'll run the same lineup, same schedule tomorrow."
