Police were alerted to a disturbance at Ms Grace's property on Sunday afternoon after neighbour Mel Te Keeti heard screaming.
Ms Te Keeti, herself a mum-of-four, had lived next door to Ms Grace for about 14 months and was shocked at her death.
"Robyn was an awesome neighbour, a really nice lady who would help anybody, anytime, anywhere. That's the kind of lady she was,'' she said.
She was "dedicated'' to her three children and known for working hard on her vegetable garden.
"People would come over and give her a hand, give her plants, and she was really enjoying that,'' Ms Te Keeti said.
"She definitely didn't deserve this - nobody does, but she definitely didn't.''
The death was the talk of the town and she was getting to grips with happened over her neighbour's fence.
A `RIP Robyn Grace' tribute page has been set up on Facebook.
"You will be dearly missed,'' says Abbey Page, who created the site.
