"We'll have hundreds of numbered sticks buried in the sand and every number corresponds to a prize - every little digger is guaranteed a prize."
There is also a chance to win spot prizes from Rainbow Springs, Reading Cinemas, Rotorua Speedway and Wonderworld Aquarium and Pet Centre.
The prizegiving will be held about 10.15am.
Mr Hickey said the beach dig had been running for six years, and at the event younger children would have a go before the older kids got their chance.
"It's a nice event for the kids."
Mr Hickey said there was also a big playground for the kids to enjoy before the dig began.
