While the auction is still more than a week away, Ms Jean is already thinking ahead to her next fundraiser.
The firm which printed her fliers without charge challenged her to do something for prostate cancer as well - so next year you can look forward to a painting featuring a telegraph cucumber and two avocados.
Ms Jean is the artist responsible for the giant (100:1 scale) plug which can be seen floating in the Kerikeri Basin.
The painting will be auctioned at 5pm on October 14 at the Pear Tree Restaurant, next to the Stone Store in Kerikeri. All proceeds go to the New Zealand Breast Cancer Foundation. For those wanting to see Helen's melons beforehand, the painting is at the Pear Tree.
