But it will also be the last time it is held, she said.
It has been run by a team of volunteers for 21 years and is a huge time commitment, she said.

"We truly appreciate your support and understanding and look forward to seeing you in January."
Hay said it had been difficult trying to organise the event under the Delta outbreak.

The Sculpture on the Peninsula event will run on January 28-30. Tickets will be on sale from November 21. Find out more on the event's website.
