Erika Fairweather has qualified for the final of the 400 metres freestyle at the Tokyo Olympics by finishing second in her heat.
Fairweather's time of 4:02:28 seconds broke Lauren Boyle's New Zealand record and Fairweather's personal best.
The 17-year-old Kavanagh College student from Dunedin is the youngest New Zealand athlete in Tokyo and has become New Zealand's strongest hope in the pool these Olympic Games.
The final will be raced on Monday afternoon (2:20pm NZ time), when Fairweather will be hoping to break the swimming team's 25-year Olympic medal drought.
