Murray will provide a brief tutorial to entrants before the competition starts.
"I've learnt a few things over the years and I'm happy to pass that on," Murray added.
Hawke's Bay Regional Sports Park CEO and Hawke's Bay Rowing club coach, Jock Mackintosh, said he was stoked Murray was attending the event.
"Eric and his pairs partner, Hamish Bond, won 69 consecutive international races including multiple world championships and two Olympic golds. It's hard to imagine that record ever being broken. He is also a 'machine' on the Concept 2 indoor rowers, so our local athletes have a great opportunity to learn from him."
Mackintosh said they were keen to attract non-rowing entrants to the event.
"Non-rowers, who use indoor rowing machines at the gym, will gain most from hearing what Eric has to say. It's an opportunity for them to dramatically lower their scores and to test themselves against those who do rowing as a sport."
The competition will take place in the new EIT Institute of Sport & Health at the park. Entries can be lodged at www.sportspark.co.nz and entry fees range from $5 to $15.
