"I can definitely get there. But this is kind of like my break I guess and i think this is really going to help me jump from the level I have been at for the last couple of years to the next open world level."
Capp has an extended build up beginning in June before the world championships with three international meets in Spain and France, along with two training camps in Spain, including one at high altitude in Sierra Nevada.
Tai Daniela coached Capp at Greerton from 2007 to 2011 and was obviously pleased to see his former charge make the "All Blacks of our sport".
"Nathan's success is down to good long-term development planning as he never swam at junior nationals and did not set a Bay of Plenty record until he was 15, but at 20 is tracking positively towards the Rio Olympics," said Daniela.
A scheduling clash at the weekend meant Capp was unable to swim his other signature event, the 1500m freestyle.
Daniela believes Capp also has the potential to meet the Fina standards in that event.
