Police have confirmed the woman found dead in the Kopurererua Stream was 84-year-old Tauranga retiree Beverley Dean.
The information comes more than two weeks after Mrs Dean's death.
Detective Alan Kingsbury said the results of preliminary post mortem report were known to police but the exact cause of Mrs Dean's death was now a matter for Tauranga's coroner.
However, he said her death was not being treated as suspicious, he said.
Mr Kingsbury said Mrs Dean, who had been out walking along the estuary not far from her home, had only been in the water a short while when her body was discovered.
