Tauranga Bridge Marina manager Tony Arnold said people on the boat desperately wanted pizza but were ordered to stay on board.
"God knows what they think of lovely Tauranga," Arnold said, but assured they had a freezer full of food and did not starve.
Arnold came into work from leave as soon as he heard about the situation unfolding to which he said at least 15 police vehicles were on-site while he was there.
"And God knows how many police, they were all over the place," he said.
He said a lot of people used their boats over the holiday time who were affected by the incident.
"Some of them separated from family members who were on board a short distance away."
He said the police were "brilliant" and his staff were outstanding in the face of what ended up being a 13-hour ordeal.
The marina staff were onsite until the incident came to an end this morning.
"The best outcome was achieved and we apologise to those affected," Arnold said.
A 34-year-old man was arrested without incident and was due to appear in the Tauranga District Court on Monday.
