Gale-force winds have caused widespread disruption and damage in rural Canterbury for the second time in little over a month.
The Selwyn District Council says there's been further damage to shelter belts and plantations, especially in the Malvern Hills area.
The latest gales have struck while farmers and foresters are still busy clearing trees felled in the wind storm five weeks ago.
Federated Farmers' Mid-Canterbury president, Chris Allen, says the wind in his area brought down trees that survived the previous storm.
Hundreds of properties in Mid-Canterbury are without power and Federated Farmers says a large area in South Canterbury, on the southern side of the Rangitata River, is also without power and there are a lot of trees down there as well.
The federation is trying to build up a more accurate picture of the latest damage impact and is asking farmers to to ring and leave details on its 0800 376 844 adverse events line.
