Timeline: How Prime Minister Jacinda Ardern's pregnancy unfolded

Prime Minister Jacinda Ardern and partner Clarke Gayford's baby is here.

It's been an unprecedented journey for the family over the past nine months, beginning with Ms Ardern discovering she was pregnant in the middle of coalition negotiations.

The news only added to the whirlwind of international media attention and scrutiny, and there was a huge amount of planning required ahead of the birth.

We look back over some of the most significant moments:

This is technically unrelated but worthy of a mention. One month before finding out she was pregnant and in the lead-up to the election, Jacinda Ardern told off The AM Show host Mark Richardson for saying prospective employers had a right to ask about a woman's baby plans.

She snapped and gave him an aggressive finger point, telling him it was "totally unacceptable in 2017" to expect women to have to answer that question.
