A United States Coast Guard icebreaker has sailed into Wellington harbour after working with New Zealand in Antarctica.
The USGC Polar Star, celebrating its 50th year of service, has operated in Antarctica for the past 55 days resupplying New Zealand’s Scott Base, among other duties.
Two New Zealand sailors joined the American crew to participate in this year’s Polar Star’s deployment, Operation Deep Freeze.
Polar Star cuts channels through thick ice, creating access for ships to reach Antarctic research stations and bases.
David Gehrenbeck, the US Charge d’Affaires, said the arrival of the ship highlights the relationship between the United States and New Zealand.
“Each time Polar Star arrives in Wellington, it’s a reminder of the strong partnership and shared commitment between the United States and New Zealand in Antarctica,” he said.
“Royal New Zealand Navy sea riders have become an integral part of these missions. Their expertise and upbeat approach are always appreciated by everyone on board.”

Earlier this year marked the end of a multi-year effort between New Zealand and the United States, with the Polar Star delivering a new pier for scientific research at McMurdo Station.
Gehrenbeck said that the ship’s mission involves more than supporting scientific research.
“It’s about making sure people and supplies can move safely, so our hard-working teams are supported and research at the bottom of the world never stops.”
In January, the Polar Star crew performed a six-hour rescue operation for the cruise ship Scenic Eclipse II, which was trapped in ice near McMurdo Sound.
Over the past decade, the ship has regularly docked in New Zealand when sailing to and from Antarctica.
