She converted at the first time of asking to win her second Manchester Open title 11-8, 11-8, 11-9 in 41 minutes.
"I'm actually quite emotional," admitted King afterwards.
"It's been a long time since I won an event, a lot has happened in my life since then. I've been through a lot of downs and to be at this point winning a tournament against the calibre of players we have on tour means so much. It's nice to have so much support, some of my team aren't here and my body is in bits so it's just so nice and emotional," said the 33-year-old from the Waikato.
"It's been three years since I've seen anyone in my family, and I love them, this is what all the sacrifices are for. I wanted to give my squash everything that I have and this one is for them and to everyone who stood by me. When you're doing well there's so many friends and people but it's those that are there when things aren't doing so well that mean so much," said King who will return home for the first time in three years for the NZ Championships at the beginning of July.
"Everyone has the World Championships at the top of their minds. I'm choosing to miss the other tournaments to be at my best for that but everyone will go about it in different ways so let's see what happens."
The World Championships are 13-22 May in Cairo, Egypt.
