Warships from Australia, Canada and the United States have arrived in Kaikoura to help with disaster relief efforts following this week's earthquakes.
They have about 660 sailors and four helicopters with them, and will be supporting the New Zealand Defence Force's efforts in the region.
Major General Tim Gall said the ships will help in the clean-up, movement of vital aid supplies and in conducting welfare checks.
"The ships, crews and maritime helicopters provided by our partner militaries have given us a great deal of flexibility in supporting the national relief effort," said Gall, the Commander Joint Forces New Zealand.
"They could assist in the clean-up, movement of vital aid supplies and in conducting welfare checks in communities affected by Monday's earthquake."
