Another piece of royal birthday cake is being offered for sale on the internet to raise money for a Masterton girl who survived a brain tumour.

Sophie King, 6, has endured 14 operations over 24 months after a tumour was discovered on her brain stem when she was 2.

Her aunt Liz King, who was one of 64 guests at a birthday celebration for Prince Charles at Government House last Wednesday, has auctioned her piece of cake from the party for Sophie.

Ms King said the latest MRI scans showed the tumour had gone but her niece was still battling her way back to full health in the wake of the illness.


"She really deserves a holiday when she's ready and I want to help make that happen for her."

The cake comes with a decorative paua and leaf garnish and a carry box branded with a royal seal. The auction had reached $75 on TradeMe by noon yesterday .

Two other cakes from the royal party also are up for auction.

A slice of the Prince's fruit cake sold on the site on Friday for $555.
