Sophie Pascoe will be looking to make it six medals from six events after adding another swimming gold to her collection at the London Paralympics.
The Christchurch teenager on Thursday shed a tear as she finished first in the S10-class 100m freestyle, setting a Paralympic record of 1 minute and 0.89 seconds.
"It was just head down and suck it up on the way back. I just really wanted that gold, that's why there was tears at the end," Pascoe, 19, said after the victory.
"It hurt a lot in the last 15 (metres) but I wanted it so bad and it showed what you want, you get."
With one event to go, the below-knee amputee has already snared three gold and two silver medals at the London Games, improving on her 2008 Beijing campaign (three gold, one silver).
Thursday's result was particularly poignant as the freestyle event had been a focus for Pascoe and coach Roly Crichton after the Kiwi finished fifth at Beijing.
"This race meant a lot to me and Roly, we've worked for two years on this, the 100 freestyle, we were fifth in Beijing and to come out with a gold here four years later, it's a great feeling," she said.
The result also saw her beat Canadian rival Summer Ashley Mortimer who has taken gold in the two London events where Pascoe finished second.
Mortimer finished 0.69sec behind Pascoe to take third place, while French swimmer Elodie Lorandi took the silver.
Pascoe's final event is the S10-class 100m breaststroke on Saturday.
At the close of day eight at the Paralympics, NZ sits 21st on the medal tally with five gold, five silver and four bronze.
Cameron Leslie set an Oceania record of 42.40sec to finish fifth in the men's S5 50m backstroke, and Rebecca Dubber was also fifth in the women's S7 400m freestyle.
At the Brands Hatch motor racing circuit, cyclist Fiona Southorn was 10th in the C4-5 women's road race while Nathan Smith failed to finish men's C1-3 road race.
A lack of wind meant no racing was possible on the final day of the sailing regatta in Weymouth leaving 2.4mR sailor Paul Francis 13th and the combination of Tim Dempsey and Jan Apel 10th in the two-person SKUD18 class.
