The SAR swimmer secured gold in the women’s 50-metre freestyle, clocking 24.41 seconds to narrowly edge out Cheng Yujie from the national team.
Haughey followed up with silver in the 200-metre freestyle, touching the wall in one minute and 54.91 seconds.
The gold went to Australia’s Mollie O’Callaghan, whom Haughey had defeated in the 100-metre freestyle a day earlier to claim her first gold of the meet.
With two golds and a silver so far, Haughey has one event remaining – the 100-metre breaststroke.
In other action, Australia’s Cameron McEvoy broke the long-standing men’s 50-metre freestyle world record.
McEvoy, the reigning Olympic champion in the event, posted a time of 20.88 seconds, erasing the previous mark of 20.91 set by Brazil’s Cesar Cielo in 2009.
