The Labour leader turned 40 yesterday, celebrating with her family.

Back at work in the Beehive today, Ms Ardern shared a photo of a special cake her team had given her.

The cake is a realistic representation of a black briefcase, complete with three 'files' of briefing notes.

"It seems entirely appropriate that this was the amazing cake the office blew me away with this morning," Ms Ardern wrote on Instagram.

"Every night they send me off with one of these briefcases, an edible one made for a very nice change! Thanks team, very grateful to work with such an amazing group of people."
