Rongoā Māori is just as good, if not better than conventional western medicine - that's according to Tanya Filia who says she's living proof of the theory.

Three years ago, she was diagnosed with cancer and given two months to live but she says she survived thanks to her regime of rongoā Māori.

She has shared the impact of Māori healing practices and says the main objective is to recognise Māori healing practices alongside western medicine.

"I was going through chemotherapy and radiation and there were symptoms and side effects and for the symptoms and side effects, I was having I was given more medications. Those medications caused issues for me it was just not quality of life. Through what I'm doing with rongoā Māori natural therapies I have a quality of life."

It's been reported that the Ministry of Health spends $1.9 million a year funding rongoā Māori services around the country. 

However, Green co-leader Marama Davidson says that's not enough. 

"It's an indication of the systemic bias that is present in the health system and across all of our public systems. What we know is that the health outcomes for Māori are not doing so well and so making sure that rongoā Māori is better supported and is also legal alongside western medicine."

It's the hope of both Filia and Davidson that rongoā Māori practitioners get more help and recognition.
