Mary Fisher is hoping to repeat an "incredible" experience at the London Paralympics.
The 23-year-old Wellington won a swag of medals at London in 2012, coming away with one gold, two silver and a bronze medal.
That included setting a world record in the women's 200m individual medley SM11 (a visually impaired category).
She described that experience as "incredible".
"To be the best in the world on that day and to be able to share it with so many people was awesome."

At last year's International Paralympic Committee Swimming World Championships Fisher showed just how much further she has developed, winning three gold medals in the 200m individual medley, 100m backstroke and 100m freestyle.
She also picked up silver in the 50m freestyle and 400m freestyle to add to her haul.
Fisher took up competitive swimming when she was nine and made her international debut in 2007, aged 14.
Despite a hectic training schedule of 14 sessions a weeks, Fisher studies arts at Massey University and is a regular performer with the Wellington Community Choir.
Last year she won the Supreme Award at the Attitude Awards for her sporting and social contribution.
"It was lovely to receive the award and I hope that it will enable other New Zealand youth who have a disability to believe that they can have a crack at whatever they want to achieve," she said.
