She says she was thinking about her great grandmother who raised her, and her grandmother, both strong wāhine.
"I can imagine her being there," she says. "They… knew how to wrap up things with their voices… this is what I do."
Her creativity with instruments began in childhood. She grew up in a house with no instruments, however her marae did have nine guitars and that is where she learnt to play. She says they would make do with what was available. "We'd pick up anything and do the best we can," she said.
Nanny Moewaka is a protector of te reo Māori. She was one of the first who helped reinvigorate the language in schools. She's semi-retired now, but spends her time teaching kapa haka, speaking at symposiums and weaving flax.
She says it's important for Māori to stand up and be heard. "I'm not afraid to tautoko any kaupapa," (support my beliefs) she says. "Māori shouldn't be shy. Don't be shy!"
