That decision has also prompted further discussions around whether New Zealand Golf could put their national women's open on the LPGA Tour, which would further entice Ko to play at the event every season.
But for now, New Zealand Golf can be thankful that their main marketing tool will attend next year.
"There is nothing like playing in front of my home fans and this makes this tournament one of my favourite events of the year," Ko said.
"I can't wait to be back home with some good friends and family, and hopefully have a chance to win my national open for a second time."
Murphy said he regularly received calls about whether they could push to join the LPGA Tour but they would likely need to triple their purse from $335,000 to north of $1 million.
"It's a possibility and there's been a lot of discussions with a lot of people in New Zealand around that, about possibly building up to that level in the next couple of years. That would be a wonderful thing if we could manage to get to that level," he said.
NZ Golf have an agreement to stage the national women's open at Clearwater until 2016 so it would be unlikely that any change would take place before then.
