Video: Joseph Millar steals the show at National Track and Field Championships

Despite having two Olympic medallists headlining the National Athletics Championships in Hamilton, it was sprinter Joseph Millar who stole the show, breaking two records over the weekend.

Millar broke the 200m record with a time of 20.37 seconds, which was .05 seconds faster than Chris Donaldson's long-standing national record of 20.42.

Donaldson, who now works as strength and conditioning coach for the Blackcaps, set the mark more than 20 years ago in Melbourne.

The 24-year-old was delighted to finish the race as he thought "none of this seemed possible on Saturday".

"Everything hurt, even my skin hurt. Why I don't know. I think it was just the adrenaline and emotion from literally running out of my skin on Friday," he said.

"I woke up this morning with a couple of niggles, but during warm-up, I felt something in my legs, and I thought 'let's get this done'.

"But, that good, I wasn't expecting."

Meanwhile, Eliza McCartney and Tom Walsh struggled to find form, but still managed to win their third and eight national titles respectively.

McCartney won the pole vault event with a jump of 4.55 metres, well short of her personal best of 4.82 metres.

McCartney was not impressed with her performance but isn't worried ahead of the Australian Athletics Championships, which start on March 26.

"It wasn't great, but that happens," said McCartney.

"I wasn't feeling it today; I was just struggling. It's important not to worry much about it because that's sport and sport doesn't always go well.

"I'm just happy to be competing and hopefully finish the season well."

The 20-year-old failed to clear 4.70 metres three times.

Walsh however stormed to victory with a throw of 21.51 metres to win another title. But the Olympic bronze medallist also performed well below his best.

"I was getting some good throws in at training, but I wasn't getting anything through the shot," said Walsh.

"For a bad day, it wasn't too bad either. If I can beat 21 metres four times without actually hitting one, that's still a step in the right direction."

Fellow Kiwi shotputter Jacko Gill did not compete in the event due to injury.
