World champion Lauren Boyle showed her class with back-to-back gold medals in world championship qualifying times on the penultimate night of finals at the National Swimming Championships in Auckland.
Boyle set the fastest time in the world this year to win the 800 freestyle, and then went straight back to the blocks to win the 100 freestyle, both in times to qualify for July's world championships.
Her efforts were matched by fellow Olympians Glenn Snyders and Gareth Kean who won the 200 breaststroke and 200 backstroke respectively in championship qualifying times.
That takes the world championship FINA A qualifying performances to five swimmers and 13 events.
Paralympics superstar Sophie Pascoe added to her haul with another world record in the 200 freestyle, her fourth of the championships.
