Valerie Adams produced a series of consistent world-class throws to win her 12th national shot put title with a best throw of 20.37m.
The Olympic champion was never going to be beaten in the event but she was pleased to hurl all six throws beyond 20.18m. Adams leaves for her Swiss base in a fortnight and will compete in the first of the IAAF Diamond League meet in Eugene, Oregon, in June.
Jacko Gill retained his New Zealand junior shot put title with throw of 20.53m, well short of his New Zealand record of 22.31m. Gill was pleased to be back competing after injury, but was hoping for a longer throw before heading to Europe for a stint of training and competition.
Gill is aiming to qualify for the world championships in Moscow later in the year.
The men's 400m final lived up to expectations and it was last year's junior champion Andrew Whyte from Otago who surged to the lead over the last 100m to win, finishing in 46.52 seconds and ahead of 400 hurdles specialist Cameron French and Daniel O'Shea.
