Jacinda Ardern shares second photo of her baby

Prime Minister Jacinda Ardern has posted another photo of her baby girl, who was born on Thursday.

The photo was taken with midwife Libby, who made Ms Ardern a macaroni and cheese after Ms Ardern mentioned a craving.

"One of the many special people we have been so grateful for over these past few months, our wonderful midwife Libby," Ms Ardern wrote.

"Not only is she incredible at what she does, this morning she made me macaroni and cheese because she heard me mention a wee craving yesterday. Thank you so much for everything Libby!"

Ms  Ardern was officially moved from the 9th floor birthing unit to the maternity ward on the 10th floor of Auckland City Hospital on Friday.

Ms Ardern gave birth to the baby girl at 4:45pm on Thursday, with Mr Gayford at her side to support her. He stayed with the mother and baby overnight.

The first photo of the baby that was used in news reports around the world showed the baby wearing three items of handmade clothing.

The baby's hat was knitted by a supporter, her baby shawl was knitted by Mr Gayford's mother and a blanket the Prime Minister was wearing was a gift from Ngāi Tahu iwi.
