Some will also go toward buying presents.
"We don't usually buy Christmas gifts - coming up to the coast and enjoying the outdoors we consider our present. It's a festive time of year and a time for giving," she said.
Customers had to spend $20 or more at a participating Rotorua business to be in the Christmas Cracker draw.
Mrs Ruwhiu's winning entry was from a purchase she made at Reduced to Clear on Lake Rd.
Reduced to Clear manager West Kuka said the win was wonderful news and it was very satisfying to be part of making someone's Christmas special.
"To help the community before Christmas and to be part of helping make someone's Christmas so much better is a fantastic thing to be involved in."
Rotorua Daily Post advertising manager Janine Davy said entries to the competition were up on last year.
She said it was always satisfying to run promotions that benefited both advertisers and members of the community.
