Eventually on her sixth championship ball, King was able to convert the third game 19-17 for an overall match time of 48 minutes to claim her first major title and become the first Kiwi PSA Platinum winner since 2003 when Carol Owens won the Tournament of Champions.
"I just kept thinking that it's the last match of the tournament – just leave it all out there," said the Waikato player. "Raneem is such a tough competitor and she showed in the third why she is No.1. She just kept coming back at me and never let it go until the end.
"I guess if you've beaten a player before then it gives you a bit of confidence, but every day is a new day and she's not No.1 for no reason, so I knew she was never going to let it go. I'm just extremely happy to win my first platinum event ever.
"It hasn't really sunk in yet, but to be on a stage like this, with such great fans means a lot. I just want to go on from here and keep playing good squash."
The victory means King becomes the fourth New Zealand woman to win the prestigious title in Hong Kong. She joins Dame Susan Devoy, Leilani Rorani and Owens as winners.
