Swimmer Lauren Boyle has made her second Olympic final of London 2012.
Qualifying fifth fastest for Saturday's 800m final with her second New Zealand record of the Games, Boyle was runner-up in her heat in 8:25.91, behind reigning Olympic champion and world record holder Rebecca Adlington.
Adlington, the fastest qualifier, posted 8:21.78.
Boyle estimates she will need to take at least another six seconds of her new national record to be in medal contention.
"I'm definitely happy with a best time and getting into the final is amazing. I was happy with that race," Boyle said.
"I'd say at least six seconds to get a medal, I really don't know if that's possible, so don't expect anything from me.
"You never really know how fast other people are going, especially in the heats, and I would expect everyone to go much faster in the final."
Taking almost half a second off her previous New Zealand record, Boyle was able to position herself in second place from the 250m split behind Adlington, where she stayed to the finish.
"She [Adlington] was quite a bit ahead of me so I wouldn't say that I was getting much off her, more like I was swimming into her waves when she was turning.
"It was nice to see someone ahead because I knew that I was on pace, but I don't think that necessarily dragged me along."
Compared to the hours which separated her 400m heat from the semifinal, Boyle has a day and a half's rest ahead of Saturday morning's medal race at 6:45am (NZ time).
And while that extra time is more suited to Boyle she said it is no advantage.
"I think it does suit me more, but at the same time everybody else has the same to recover so it's about maximising that time and getting the most out of the recovery that I can.
"It's going to be a case of really being in my own body and not caring where they are in relation to me."
Elsewhere, an agonising three-hundredths of a second were all that kept Melissa Ingram out of the 200m backstroke semifinals.
Ingram posted 2:10.63, to finish one place outside qualification in 17th.
The Auckland swimmer's personal best of 2:09.13 would have put her through as the eighth fastest qualifier.
"It wasn't too far off my PB, but I'm disappointed to miss the semifinal by such a tiny margin," Ingram said.
Marking the end of her Games, Ingram said her thoughts must now turn to the world championships.
"I'm going to head back to Auckland and take a short break now, then I'll re-focus for the world short course championships in December," she said.
Daniel Bell failed to progress in the 100m butterfly, dropping out of the heats in 37th.
Bell's time of 53.76 was two tenths of a second off his personal best.
The time also sits outside that of Andrew McMillan's at Olympic trials - meaning McMillan earns the butterfly leg of the men's 4x100m medley relay on Sunday morning.
Bell's Olympics is now over.
