"This is a really good opportunity for young people in particular to engage with archaeology and Maori heritage in a fun, hands-on way," she said.
"We'll be carefully using an existing stone fish trap, which we believe is well over 150 years old, to show people how they worked, while also giving them a taste of this particular aspect of Maori heritage."
Participants would learn how the fish trap was constructed, how it worked and (hopefully) how effective it was.
"Last year we caught a good number of fish using it. We'll be looking to repeat that result," she said.
The free event will start at noon and run until about 2.30pm, followed by a short tour of the nearby Edmond's ruins.
