Prime Minister Jacinda Ardern has been admitted to Auckland Hospital.
Expecting her first child, she was expected to give birth on June 17th.
Deputy Prime Minister Winston Peters will step up as Acting Prime Minister while Ms Ardern is on maternity leave.
Ms Ardern has said she will take six weeks off before returning to work.
She is only the second leader in world history to give birth while in office. Pakistan's former leader Benazir Bhutto gave birth to a daugher in 1990.
We wish Jacinda and Clarke all the best and we're super excited for the baby!!
