Fundraising manager Shirley Collins said: "Every year this is an exceptional event, and we encourage everyone to make a fun afternoon of this event by joining up with friends, pooling money and bidding on lots as groups.
"There will be a lot on offer, and participating in groups is a good way for people to get their hands on some unique and stunning wines without breaking the bank."
Cranford Hospice general manager Helen Blaxland said: "The auction format will be kept simple, and will include an afternoon pre-tasting function, food and music, followed by the auction itself, all held at the Hawke's Bay Racing Centre.
"It's going to be a nice casual environment where everyone is welcome, and we hope a wide range of people will come along and enjoy it."
Mrs Blaxland said wine growers had shown huge support with generous volumes on offer, and it makes sense to bid in groups.
"It's also a good chance for people who have used Cranford Hospice to come along and perhaps get special labels made for winning lots in memory of loved ones."
Auctioneer for the event will be retiring Napier MP Chris Tremain.
The auction has raised more than $2 million for Cranford Hospice over the past 22 years, with funds helping to keep palliative care services free for terminally ill patients.
