"The result? Higher rates of breastfeeding, immunisation and uptake of other support like dealing with the consequences of trauma, or family violence and even budgetary advice," Ardern continued.
She said she believed in the power of intervention and that supporting mothers helped children to thrive.
"And so in this Budget we begin the journey by putting $10 million into extending Nicky's programme into three sites across New Zealand – which I hope is just the beginning."
The programme falls into the category of "Taking Mental Health Seriously", in the Budget, and Ardern said during her speech that the best place to start was with mothers.
The money will enhance support for parents and whānau who have mental health or addiction needs during pregnancy and for the first two years of a child's life or after a still birth.
It will also help keep at risk children safe, a joint press release from six ministers, including the Prime Minister, stated.
The programme has been allocated $10 million in the Budget to roll out in three locations in New Zealand.
