"I'm planning to serve up some Dutch bruschetta and melon and I will also be doing something with some fresh John Dory fish that has just arrived...the rest is a secret."
The annual event was dreamed up by Gordon to raise funds for Leukaemia & Blood Foundation New Zealand. More than $1 million has been raised since its inception in 2007.
Gordon has a close connection with the cause. In March 1995 his sister Tracey was diagnosed with acute myeloid leukaemia and he donated bone marrow to save her life.
The transplant was successful and his sister travelled from her home in Australia to attend the dinner.
"It is 21 years since the transplant, and it is fitting that Tracey should be here to celebrate," Gordon said.
