"Police are making enquiries into the circumstances of the death and the coroner has been informed."
Waihoro/Spreydon-Cashmere Community Board chairwoman Karolyn Potter said the community was resilient and would rally around the family.
"This is a sadness that's beyond talking about."
Spreydon ward councillor Dr Melanie Coker said she had only learnt about the "absolutely heart breaking" incident after seeing media reports, but sent her condolences to the family.
