The woman, in her 20s, received minor concussion and injured her shoulder on May 17.
She complained to the Department of Labour, which visited the $18 million aquatic centre yesterday.
Lakes Leisure management agreed to shut the hydroslide, according to Queenstown Lakes District Council community services general manager Paul Wilson.
The hydroslide was closed on December 9 last year after Lakes Leisure confirmed up to 69 customers had received minor injuries since it opened on May 31, 2008.
After being opened "sporadically" over Christmas, the slide was back in action on January 23 this year.
Lakes Leisure facilities general manager Cam Sheppard told the Otago Daily Times last night there had continued to be issues, although the number of "relatively minor" incidents had reduced "dramatically" since safety measures had been implemented.
Those included placing a height and age restriction on the fast slide and increasing flow rates.
The woman injured on May 17 had complied with those measures and had been given safety advice by a staff member at the top of the slide.
Mr Wilson said the district council had commissioned an independent review of the slide with Australian company Leisure Engineering.
It would review the entire slide including its design, water flow and, in particular, one of its corners.
In a press release yesterday, he said the slide would remain closed until an appropriate solution for safe public use could be identified and implemented.
"I am confident that Lakes Leisure has exhausted all practical minimisation and supervisory steps and that the next step is most likely a reconfiguration of the slide."
It was disappointing that the slide could not be used to its intended capacity but public safety was paramount.
"The issue has been ongoing and we need to get it right," he said.
Wakatipu St John ambulance team manager Alana Reid said she was not aware of any callouts to the aquatic centre in recent months.
