"Our current premises are inadequate - we have simply outgrown our environment," chairwoman Paula Wade said. "We are so grateful to Suzuki, David Jones Motors and our other generous sponsors to ensure we raise at least $50,000 to help us move."
She said that Women's Refuge in Whanganui processed approximately 1500 police incident reports each year, but received government funding for only 49 of those reports.
Great Ball committee chairwoman Sharon Warburton said the funding shortfall was one of the reasons for the creation of The Great Ball.
"We need to raise a significant amount of funds to allow Women's Refuge Whanganui to help more women and children."
Tickets for the Great Ball have sold out but Ms Warburton said people could still bid for the car or any of the many other auction items on offer, or make a donation.
