Police have now identified the woman whose body was found near Waiheke Island yesterday.
They have contacted her next of kin.
Police earlier released photos of the woman's unique tattoo, hoping it would help someone to identify her.
Her body was spotted in the water by a member of the public about 2km north of Korakorahi Point, near Onetangi Beach at approximately 1.20 pm yesterday.
The woman is believed to be in her late 50s or early 60s and was wearing a blue, one-piece swimsuit.
She has a distinct tattoo on her left forearm of a Latin-looking design. It is a 'greater than' symbol inside a square with disjoint side.
"A post-mortem is expected to take place today, however, based on initial enquiries police do not believe there are any suspicious circumstances relating to her death at this stage."
Anyone who believes they can identify this woman or has any information should contact police on 09 302 6640.
