A 200 thousand dollar boost for storm-ravaged Nelson region.

The Government's pumping cash into the Nelson Tasman and Marlborough area - for immediate help after prolonged heavy rain, flooding and high winds.

Emergency Management Kieran McAnulty says the weather's caused considerable damage and been extremely disruptive.

He says it's still too early to know the full cost but this first contribution to the Mayoral Relief Fund is a start and will ensure there's little delay in getting immediate support.
