A super-sweet fundraising effort has netted a children's charity more than $1500.

Jaedyn and Ruby Marris were raffling off a 4.5kg Toblerone bar to raise money for Heart Kids in memory of their late sister.

The siblings, aged 7 and 4 respectively, made the trip to the Whangarei Police station on Friday afternoon to get a police officer to draw the raffle.

Constable Steven Coe obliged, and plucked Susan Barker's name from the Cat in the Hat hat which Ruby had all the names in.

The siblings' mum, Taryn Marris, said the raffle had raised $1550 which far exceeded any expectation she had.

Jaedyn thanked everyone for their support.

Ruby won the giant block as a spot prize in a Christmas promotion at Pak'n Save. She wanted to break a piece off and send it to heaven using helium balloons for her sister.

Mrs Marris suggested the family could do that with a regular size block of Toblerone, but use the giant one to raise money for charity, and Heart Kids was the obvious choice.

Taryn and husband Clint's first child Belle had a congenital heart condition and was stillborn about eight and a half years ago.

A post on Facebook started the raffle, which ran for just over two weeks. After finding a winner on Friday, the Marris' headed off to finish what they started.

The siblings tied five helium balloons to a piece of Toblerone and sent it free, to float to Belle in heaven.

Mrs Marris said the cardboard screenshot of the fundraising account had been ordered, and Jaedyn and Ruby would be taking it to Auckland to present it to Heart Kids in the next couple of weeks.
