A $2 entry fee gave diggers the chance to win prizes such as a beanbag, crystal glassware, clocks, health and beauty products, retail vouchers, and lots of golf balls.
Lisa Lyall, Kaka Point Community Group events manager, said the entry fee was kept low because the event was about getting back to family values.
"Everything costs families lots of money. Anyone can come and do this, and it costs a family of five $10."
Money raised would go to refurbishing the Kaka Point tennis courts, estimated to cost $10,000.
"The tennis courts are used by loads of holiday-makers. All the [wire netting] round the place needs replacing, with new poles."
The main prize was a 81cm LCD high-definition television.
Its chip was unearthed after almost an hour of solid digging by Bailey Povey, of Kaka Point.
It was buried deep in the hard sand, he said.
Shelley Russell, Mr Povey's girlfriend, said the couple did not have a television and were happy to have won it.
"I was nearly giving up, but . . . I knew he had the strong arms to do it."
