The owners of The Heartland Mueller Hotel are suing two West Coast councils for flood damage.

Following heavy rain in March 2016, the hotel was flooded when the nearby Waiho River burst a stopbank. The hotel claims it lost over $30m in damages as a result of the flood, which deposited gravel throughout the hotel and damaged concrete in the car park.

The Scenic Hotel Group, which owns the Heartland Mueller, is suing the Westland District Council and the West Coast Regional Council.

The group is alleging that the stopbank, which was on district council land and part of the regional council's flood management scheme for the Waiho River, was not up to scratch.
