Opo the dolphin
A DigitalNZ Story by Zokoroa
The playfulness of Opo who was mourned nationally on her death on 9 March 1956
Opo was a young female bottlenose dolphin (Tursiops truncatus) that began frequenting the waters at Opononi on the Hokianga Harbour in Northland from March 1955 until her death on 9 March 1956. Photographs of her playfulness appeared in the newspapers and she became a tourist attraction. When Opo was found dead in a tidal rock pool, the news was reported nationwide which led to messages of sympathy. A funeral was held and Opo was buried in a special plot next to the Opononi War Memorial Hall.

Manatū Taonga, the Ministry for Culture and Heritage
Writing in the July 1958 issue of 'Te Ao Hou,' Piwai Toi, one of the first people to see Opo close up, recorded his thoughts:
"...Why did the dolphin come to live in the Hokianga River in the year 1955? She was seen following rowing boats during February of that year. On Easter Saturday in March 1955 a memorial for Kupe was unveiled, after whom this river was named the Hokianga, or 'Return of Kupe'. Mr Hohepa Heperi, a Maori elder who was brought up in the Hokianga, said to us: 'Opo is the fish of peace, a legacy from Kupe.' She died on some rocks above Koutu Point, about three miles up-river from Opononi. The Maori name for these rocks is Te Kauere o Kupe. It was towards the end of March 1956 that Opo died. These coincidences are certainly strange....My own humble opinion, for what it is worth, is that she committed suicide. I base my conjecture on two points. Opo was a female dolphin and there was no male to keep her company... As she was a lone dolphin the urge to reproduce like any other animal could not be satisfied...When this urge was not satisfied she committed suicide by deliberately getting herself stranded..."
