The state's 20 centres provide tailored care for women and assist with physical, mental, sexual and reproductive health services.
More than 50,000 women, predominantly those who are at-risk and vulnerable, access face-to-face support each year.
The upcoming state budget will allocate an additional $34.3 million for the health centre program over the next four years.
Centres in Bankstown, Blacktown, Cumberland, Fairfield, Liverpool, the Hunter and Penrith - as well as the Central Coast, Illawarra, Lismore, Shoalhaven and South Coast - are set to benefit from the boost.
Health Minister Ryan Park said the centres offered a range of services and had a positive impact on women's health outcomes.
"This investment will ensure more women have access these key health services across NSW," he said.
The funding is expected to help increase staff numbers, reduce waitlists for counselling appointments, offer services to more women and adapt existing support to address emerging demographic trends, population growth and complex health issues.
Women's Minister Jodie Harrison said the centres were crucial to women's health care and provided vital support for those escaping domestic and family violence, from lower socio-economic backgrounds and in regional areas.
"They provide a welcoming environment which empower women by promoting their physical, mental and emotional wellbeing," she said.
The Minns government's first budget will be handed down on Tuesday, September 19
