The Prime Minister says it's crucial we reinforce New Zealand's important role in the icy continent.
Jacinda Ardern arrived in Antarctica on Wednesday a day later yesterday than planned and speaking from Scott Base said other countries are increasingly contesting territory there.
The PM says she knew about the importance of international cooperation in theory but being there has reinforced just how important it is.
Jacinda Ardern spent yesterday exploring further afield from Scott Base, including the Dry Valley and Terra Nova Hut.
A highlight was visiting the hut of her 'childhood hero' Ernest Shackleton.
Today the Prime Minister will visit scientists in the field and the Ross Island Wind Farm before flying home.
