All funds raised will go to Mary Potter Hospice in Wellington.

Winning bidder Paul will get the sign as individual letters on a steel frame backing. Wellington Airport will cover up to $1500 for the cost of the freight.
Paul took the lead in bidding this morning before another user tried to swoop in at 10.58am.
But that was quickly matched by Paul, who, having been a member of Trade Me since 2003, has won 26 auctions and received glowing reviews as a buyer.
Airport spokeswoman Kat Linlott said the All Blacks sign had drawn lots of attention.
She said the sign had been put up during the first few weeks of the tournament and was taken down last week.
It is to be replaced by a new sign - Wellington - with the last three letters styled as if they are being blown away.
All Blacks manager Darren Shand said the original sign had been a great show of support for the team during the tournament.
"It was a very cool gesture, was very much appreciated by the team and overseas fans flying in for the Wellington test matches were left in no doubt which team Wellington was supporting," he said.
He said the funds raised were going to a fantastic cause.
Spokesman Graham Ford said they were thankful for the gesture and the funds raised would be greatly received by staff, but particularly patients and their families.
"Money raised from the auction will help provide medicine and medical care for those most at need and support for their families."
