The Red Cross in Samoa is still delivering water to about 5000 people a day after September's tsunami.
Many people moved to higher ground in the wake of the disaster, where they still live in makeshift shelters, while rebuilding their homes.
The operations managers of the New Zealand Red Cross, Andrew McKee, says volunteers still need to deliver water and it is being trucked in daily to the relocation camps.
He says work is under way to pipe supplies from a fresh water lake to the relocation areas. It is expected to be completed in a month.
