Extreme winds are battering Wellington, Wairapa and the South Island. 

Winds of up to 150km/h are expected today as red strong wind warnings are in place for much of the South Island's eastern regions and southern parts of the North Island. 

More than 100 flights have been cancelled, along with some of the planned strikes in tehe affected areas.  

Transpower Executive General Manager of Grid Delivery Mark Ryall told Kerre Woodham that three the Canterbury to Nelson power lines 'trip out' due to the extreme weather.
