The Ministry of Health had been told to work with Health New Zealand on preparing for the change.
Costello would be the minister responsible for the bill.
She described it as a “practical and compassionate step” that put women and their wellbeing at the centre of the health system.
“We recognise that childbirth is different for every woman, but no one should be made to feel they have to leave hospital or a birthing unit before they are ready.
“By guaranteeing every woman up to three days to rest, recover and bond with their baby, women will have the choice to be where they feel most comfortable.”

Wedd, the MP for Tukituki and a mother of four, said she was proud the Government had adopted her bill.
“Once implemented, the change will make a real and lasting difference for mothers, giving them the time and support they need in those precious early days.”
