Mya has continued her medal run at the Australian age championships in Adelaide.
Mya led a run of five medals by the New Zealand swimmers in the last two finals sessions at the championships.
After a victory in the 400m individual medley earlier in the week, the 15 year old won two silver medals to conclude the championships.
She was second in the 200m individual medley in 2:18.61 which was 5/100ths of a second under the long standing national age group set by Atlanta Olympian Anna Wilson in 1993.
Rasmussen, from the Kiwi West Aquatics club, also won a silver medal in the 200m breaststroke in 2:25.33.
