Erika Fairweather has advanced to the semifinals of the 200m freestyle at the Tokyo Olympics.
The 17-year-old Dunedin swimmer clocked a personal best time of 1min 57.26sec to qualify 14th for tomorrow's next round.
She finished fifth in her heat, which was won by American star Katie Ledecky.
The semifinals will be held at 1.30pm tomorrow afternoon (NZ time).
Fairweather is the reigning world champion in the event, having won the under-18 world title as a 15-year-old in 2019.
It follows a superb opening to the Games, in which the Kavanagh College head girl reached the final of the 400m freestyle.
She took four seconds off her personal best in swimming a time of 4min 02.28sec in last night's heat, qualifying fourth for the final.
It also lifted her to fourth in the world rankings for this year and broke Lauren Boyle's New Zealand record.
This afternoon she finished eighth in the final.
