The Government has committed a further $1.2 million in emergency aid funding to help relief efforts in the Solomon Islands.
The announcement takes New Zealand's total to date to $1.5 million.
Heavy rain last week from a tropical depression caused severe flooding, particularly in Honiara after the Mataniko River burst its banks, washing away homes and bridges.
More than 50,000 people have been affected by the flash floods and an estimated 10,000 are sheltering in evacuation centres.
The additional funding from New Zealand would be used to provide relief supplies and help restore health, water and sanitation systems, Foreign Affairs Minister Murray McCully said.
