'He kōtuku rerenga tahi' is a whakatauki or proverb, which means 'a white heron's flight is seen but once'.
It is used to indicate a very special and rare event.
On February 11-13, Te Taiwhenua o Heretaunga hosted one of those very special and rare events for students ranging in age from 14-17.
Around 20 young scientists joined in a research project of Te Kauae a Māui, commonly known as Cape Kidnappers.
A special team consisting of the University of Otago Archaeology Department, Heritage New Zealand, the Conservation Department, the landowner, Te Taiwhenua o Heretaunga and mana whenua representatives, have been working on this research project.
