Sophie Pascoe of New Zealand won her second gold medal in world record time at the Paralympics in the women's 100m butterfly on Saturday.
Having set a world record time of 1.04.97 in the heats, Pascoe swam the final in 1.04.43 to collect her second gold in London.
Pascoe, 19, finished 4.12 seconds ahead of Oliwia Jablonska of Poland and said she raced the clock, with her opposition just not in the same class.
It is her third medal of the Games.
Meanwhile, silver medallist Mary Fisher of Wellington won bronze in the S11 women's 50m freestyle heat.
Fisher, also 19, earlier set a new Oceania record in her heat.
It is her first Paralympics.
Cameron Leslie came third in his S5 200m freestyle heat and sixth in the final.
New Zealand finished day three in 15th place on the medal table with two gold, two silver and three bronze.
Pascoe now has two days off and plans on staying away from the pool to keep herself fresh for the next three events.
"We don't come to the Olympic pool unless we need to be here," she said.
"It is a long time to be competing for 10 days and by the time the 10 days come up, you don't want to be too waterlogged and not feeling the best in the pool."
