Mr Sweetman said ground announcer Craig Boyden added to the atmosphere of the day, stepping in at short notice.
Mr Boyden admitted his was an impromptu performance.
"I had one boo, boo, but it was certainly was a great day - one of Dannevirke's finest. I want this to become a regular event here.
"Rugby Park was looking good. Groundsman Buck Mackay did a good job.
"The referees were worn-out in the heat, but we had some banter about eating pies on such a hot day."
Mr Boyden said one of the standout players for Hawke's Bay was Mason Emmerson, who impressed with his play and attitude.
Conrad Waitoa, manager of the Hawke's Bay sevens team, said Dannevirke was a great location and he was keen for the competition to return.
"If we could get teams from Wanganui to come along we could make a real cool day of it," he said.
