Work has begun on getting help to those affected by the weekend's floods.
The Red Cross has set up an appeal fund, Wanganui Mayor Annette Main has established a mayoral relief fund and the Manawatu Whanganui Regional Disaster Fund has been activated. A number of organisations are also collecting food.
New Zealand Red Cross secretary general Tony Paine said the organisation's emergency response teams were busy over the weekend responding to the floods, but as the scale of the damage becomes apparent, a comprehensive recovery job would be needed.
"The floods are the worst disaster to affect New Zealand since the Canterbury earthquakes. Thousands of people will need help to get their lives and livelihoods back on track," Mr Paine said.
An appeal has been launched to help those affected by the floods in Wanganui, Rangitikei, Taranaki and, earlier in the month, Hokitika and Dunedin.
