Those in the North Island are this morning waking up to fallen trees, power outages, blocked roads and property damage after powerful gale-force winds battered many areas.

Auckland Transport reports that the storm is causing issues on the rail network, with western line services terminating in Henderson with some bus replacements.
There may also be delays at other stations because power may be out, AT said, and the network is being assessed.
Conditions are easing across the North Island but there's still a chance of heavy rain around Taranaki, Whanganui and the Hawke's Bay hill country.
No state highways are closed, except the Desert Road which is closed due to snow.

There are also warnings in place for the Crown Range Road, Milford Road, Dunedin to Waitati Highway, SH80 and SH77.
