Another day, another medal, for Sophie Pascoe at the London 2012 Paralympic Games.

The 19-year-old swimmer twice lowered the world record on her way to winning gold in the S10 women's 100 metre butterfly.

"Didn't do the best touch into the wall at the end but I'm a critical person about myself, but I can't complain - a new world record and a gold medal," she said.

Pascoe finished more than four seconds clear of second to have two golds and one silver after just three days of competition.

Mary Fisher claimed bronze in the S11 women's 50 metre freestyle taking New Zealand's medal haul to seven.
