But new mother Meg Waghorn, of the Lower Hutt Parents Centre, said although the money was welcome, the investment was not a fix-all.
"Undoubtedly it will be beneficial, I think it will be welcomed by everybody who is concerned about the maternity care in the Hutt.
"But I would also say that anybody who has spent much time around these issues would also know it's not going to be a magic bullet, it's not going to be enough to fix all the problems - because there are problems in several areas."
Not only were staffing levels "crucial", but staff also needed "appropriate facilities so that they can provide the best care they're able to".
She said the facilities were run down.
"I hope that this is a little early signal that central government has listened to the concerns around the country about maternity."
Waghorn said negative experiences with maternity services had a "ripple effect", and it was important government recognised that.
Midwifery staffing also needed to be "resolved with extreme urgency".
The Government's investment into Wellington region health services comes to $45.8m, spread across Hutt Hospital and Wellington Regional Hospital.
"The $25 million allocated to rebuild Hutt Hospital's acute mental health unit – Te Whare Ahuru – will be hugely beneficial to staff and clients of our Mental Health, Addictions and Intellectual Disability Service," Dougan said.
TWA provides inpatient mental health services primarily to Hutt Valley and Wairarapa DHB clients.
"This funding will assist with the development of a fit for purpose facility to provide a safe, more therapeutic and culturally appropriate environment with improved whanau spaces."
Clark said it was the Prime Minister's ambition to make New Zealand "the best place in the world to be a child".
"To support that, we're investing in expanded neonatal intensive care to help our most vulnerable new-borns, and in maternity care for expectant mothers."
