"I'm so grateful to have this place," she says.
One of the other eight residents suggested, to help Sita through a frightening time, she write up a wish list.
"I wrote that I wanted to see my family. That was between me and the universe and I kept it in my room, but someone saw it."
Her house mates set about raising funds to bring the Newmans to Sita; a cause Saturday's concert will also aid. She says she drifted in life, working in hospitality, retail and as a fitness instructor. She has also volunteered at the Himalayan Trading Post shop in Whangarei. "I never felt like I found my calling. I wasn't focused, I was spiritual but had no particular religion."
Back when Sita was in her early 20s, she watched her mother go through a raft of painful treatments for the same cancer, and yet still die. Her mother's experience destroyed Sita's faith in medicine.
Aggressive intervention was not for her, she decided, when she had inkling something was not right in her own body.
Nor was "sharing" her condition with others, no matter how well meaning the support they might offer.
Late in her journey, she has "made peace with the medical world" and learned how "beautiful and caring" the people are who work there.
"I'm not really religious but I believe 'God' is love, and I've learned that you can't be loving and judgmental at the same time."
Father Steve, stepmother Jean and half-brother Jivan Newman shed tears of love and grief as Sita talks.
They are devastated she became so ill before telling them, broken hearted they have less than two weeks here with her.
"She's an angel, there is no doubt. I still hope things might change. I might be a fool, but I still have to believe that," her father says.
The saddest thing Sita feels as she contemplates dying is that she didn't spend more time with her brothers.
"But I feel so blessed to have this time," she says.
"After trying to push this thing away it's been a really good journey to let people in and let them love me."
