Hawkes said he was surprised when he was notified by Tennis NZ.
"I was not expecting it as I didn't know something like this existed," he said. "But looking back I do feel proud to have won that many titles. It's one of those things, when you start off you don't really expect to end up winning that many.
"It is just one match at a time really and the years tick by and all of a sudden you have got 36 titles."
Rating which title was the most memorable was not easy but the win in Hawke's Bay before his heart surgery in October 2012 was special. "I was having trouble breathing and was running out of puff. It stems back to 2004 when I was going to Philadelphia to play in the worlds and I caught a virus from some lady in the plane flaked out next to me. I don't think I ever recovered and I think that is how I damaged my heart valve."
Hawkes had a lifetime playing top provincial tennis, and he also played for New Zealand in the 1970s, so was always going to be successful at senior level. But overcoming the mental challenge of getting back into competitive sport after major heart surgery might well be his greatest achievement.
