New Zealand has just deployed three more groups of personnel to assist in the tsunami disaster relief effort, Foreign Minister Phil Goff and Defence Minister Mark Burton said Monday.

Burton said 30 members of the Defence Force Light Medical Team were deployed to Banda Aceh, Indonesia, where they would work in the public hospital.

Their first task, now underway, will be to clean up the facility, which was extensively damaged by the tsunami, he said.

The Defence Minister said the team would work alongside an Australian Health Support Company to provide primary health care and environmental health support.

The Company is to operate a 90-bed facility with level one through to level three medical and surgical capabilities.

Burton said a key concern at this point is to prevent the outbreak and spread of disease through the conditions left behind by the tsunami.

"Five Defence Force staff have also been deployed this weekend to Medan to work in the Taskforce Headquarters, which is charged with coordinating Australian and New Zealand military units involved in the relief efforts in Aceh," he said.

Goff announced a strengthening of the New Zealand Disaster Victim Identification team already working in Phuket, Thailand. Four additional staff, consisting of two forensic dentists, a mortuary technician and a psychologist, have arrived in Thailand to supplement the team.

"Police are planning to rotate the team every three weeks. The team has a particularly tough job to do in extraordinarily unpleasant circumstances, and regular rotations are necessary," Goff said, adding The psychologist would work with the teams to help members cope with the grim task they were performing.

"I would also like to acknowledge the on-going generosity of New Zealanders who have now contributed over 9.3 million NZ dollars (about 6.5 million US dollars) to the disaster relief effort," Goff said.

He said the New Zealand government would this week continue to work on its proposed package of assistance that would recognize the need for on-going reconstruction and development assistance aswell as the immediate disaster relief efforts.

An announcement will be made on the package in due course," Goff said.
