Despite Sculpture on the Peninsula being cancelled less than a week before opening night, $75,000 was able to be raised for Cholmondeley Children's Centre.
The organisers moved to contingency plans when the country moved to the Red traffic light setting in late January.
Within a week, more than 2000 photos had been taken and the items catalogued and loaded to online art sales website NZArtbroker.
The online event generated the highest level of sales in the event's 22-year history, but overall takings were still significantly down due to a number of fixed costs and the loss of gate and food & beverage sales, organiser Gill Hay said.
"Everything had been going beautifully and we were so organised, and then we got the news. It was all hands to the pump to make sure we could honour the sculptors that had done so much already, and to continue to support the children of Cholmondeley," she said.
