Dean Murphy, New Zealand Golf's chief executive, believed that while HPSNZ's investment would still be well-placed given the high costs involved in competing at the top events internationally, the time was right for New Zealand Golf and Ko to move ahead without HPSNZ financial support.
"Lydia is a fantastic ambassador for New Zealand on the world stage. She loves New Zealand and loves to represent us around the world. As a nation we have loved watching her excel,'' Murphy said.
"Our focus at New Zealand Golf is, and always has been, developing and supporting golfers who have the ability to compete and succeed on the world stage.
"All previous investment from New Zealand Golf and HPSNZ has been based on demonstrated need and has been completely fit for purpose. It has been disappointing to see the recent discussion in the media on the merits of this funding, particularly as it has already provided significant returns. Lydia has proven what an incredible competitor she is with her successes so early in her career as a professional golfer.
"We trust that by ceasing all current HPSNZ funding, the discussions in the media will now rightfully return to Lydia's outstanding ability on the golf course and the wonderful promotion she is providing for the game of golf and New Zealand as a country.''
HPSNZ hopes to continue supporting Lydia with information and knowledge to help with her preparations for the 2016 Rio Olympic Games, as this will be an environment she hasn't competed in before.
New Zealand Golf and Lydia Ko have no further comment to make on the funding programme from HPSNZ.
