Thompson-Newth will remain as a registered player with the Wanganui club, although she does not play in all of the events as she is also a full member of the Castlecliff Golf Club.
She was informed in March that the rule change for the senior women's competition meant the title could only be contested by sole-Wanganui club members.
"Just because it's my secondary club, they wanted to make it just your primary course [players]."
Thompson-Newth has always been able to play for the Castlecliff titles, despite her multiple memberships.
The Wanganui Chronicle understands the December meeting of the Wanganui club's women's committee came down to a casting vote by the chairperson to make the rule change.
Thompson-Newth said the matter was raised with club manager Keith Stewart and the decision was soon overturned.
She accepted that and just wanted to move on. "They just apologised for everything and said I can play if I want to.
"The men didn't really know about it until we brought it up."
Stewart was reluctant to discuss the matter yesterday, but did confirm Thompson-Newth's version of what had happened.
"The matter is water under the bridge," he said. "Yes, there was a little bit of a misunderstanding going on and as soon as I became aware of the matter, I contacted some of the other senior officials at the club and we put it back together immediately."
Thompson-Newth, or any registered Wanganui club member, would "absolutely" be eligible to qualify for the senior men's or women's championships, Stewart said.
The teenager first won the Wanganui club's senior women's title in 2011 at the age of 16, ending the decade-long domination of Caroline Scott, overall a 15-time champion.
Thompson-Newth retained the title in 2012, again beating her own Manawatu/Wanganui representative manager in Scott to cement her place as the heir apparent, and has not looked back since.
She flew out of Wanganui yesterday to compete at the New Zealand Amateur Championship at the Nelson Golf Club links.
