"I felt really strong out there today and got off to a good start in the swim leg which always helps and was able to keep the margin over James throughout the rest of the race," said O'Grady.
"I really enjoy this course and particularly the final leg around the base track of the Mount."
"I think they have done a great job at tidying it up because the surface was way smoother this time than in the past, and it makes it easier for us to be running on undulating, softer surface than pounding the roads like the rest of the course."
Amelia Rose Watkinson from Auckland easily won the women's elite race.
Watkinson was making her Tinman debut and found the swim leg a real challenge in cold, windy conditions.
"I am definitely not a swimmer but I got to the front which was great because it gave me a chance to play with the waves rather than other people's feet."
"I prefer the half and standard distance, as well as hills rather than flat, but I thought I would give it a go and work on my weaknesses which we are told to do."
"I am looking forward to coming back to Mount Maunganui in January for the half."
