The New Zealand government says it will provide a temporary bridge to maintain the link between the airport and Honiara's centre following recent flash floods in Solomon Islands.
A old Bailey bridge over the Mataniko River was destroyed in the flooding nearly two weeks ago and only other over the river was damaged.
The New Zealand Foreign Minister, Murray McCully, says a new Bailey bridge will ensure transport links are maintained while the second bridge is repaired.
He says the bridge components are expected to be shipped in the coming weeks.
Mr McCully says New Zealand will also deploy two teams of emergency management doctors and nurses, logisticians and support staff to assist local authorities.
He says the main hospital in Honiara is stretched and there is a serious risk of waterborne disease.
Two Australian doctors are to join the New Zealand medical team.
New Zealand has now contributed about 2.3 million US dollars in support for the Solomons' recovery from the flooding.
