"I had to work quite hard on the swim because I know Owen is a good swimmer and he was motoring," said Pugh.
"I made sure I stayed beside him and got hold of his feet but even that was quite tricky because he was going so fast.
"I took the run pretty steady and I felt a bit horrible on the hills, and the guys were gaining on me, but I kept the pace honest, but not fast, and Owen dropped off about halfway round. When I saw that I thought I had better get rid of him for good so I went hard then and managed to drop him and Aiden (Dunster) to go ahead to win.
"I am very happy with how the season has gone, particularly winning the Surfbreaker and today because these guys are pretty quick."
While Pugh is relaxing, the season is still building for Mount Maunganui's Mann, who is competing at the Long Distance Triathlon World Championships in France in June. The distances are imposing - a 4km swim, 110km bike and 30km run - so the recent triathlon series has been ideal training.
"This is sort of the middle of the season for me and it is all buildup between now and June," said Mann, who is from the Mount.
"The races have been part of the training for that. I am really happy with how that has gone but I have not done any speed training at all so it is really good to come out here and win."
Mann won in 1h 05m 53s, with Hamilton's Nikki Edwards second (1h 07m 48s) and former world champion Alison Hamilton third (1h 09m 17s).
