The work beginning at Broad Bay Boat Club comes after eight years of planning.
The club received funding of $150,000 from the Otago Community Trust and $50,000 from the Alexander McMillan Trust two years ago, which went towards the cost of building the new wharf.
About 60 piles, each 9m long, would be erected to provide the foundations of the new wharf.
He was pleased to see work being done after so long.
"It’s amazing and it is such a huge thing for the community, it really is.
"So many people are going to be happy to see it go in," he said.
The group would need to raise a lot more money to cover the $1 million price tag for the entire project.
Mr Patterson hoped that goal could be reached.
"Our funders have been very generous so far.
"We’re hoping now the project has started we can keep the ball rolling."
