Mr Hindmarsh said he could have gone on a bit longer but had drunk too much milk before the start of the heat and his stomach was too full to continue.
"I really love my chillies and at one stage thought I could win it. But I just got too full and couldn't fit anything else in.
"I'll definitely give it another go," he said.
However, it was a big win for the champ who had come third at a recent heat in Paihia and had to win in Rotorua to qualify for the finals.
Mr Shotter said he did not prepare well for the Paihia heat but had his game face on for Rotorua.
"My mind was not in it and my preparation was pretty bad, but I got it together. It's got a lot to do with mind over matter," he said.
Competition organiser and Fire Dragon Chillies owner Clint Meyer said while the competition was a lot of fun and competitors did it mainly for the glory, this year there was a serious side to the competition as he was also raising funds for Lifeline Aotearoa, a suicide prevention and counselling service.
Mr Meyer said a competitor and friend had recently taken his own life and he wanted to bring attention to the issue of suicide in New Zealand.
"We don't talk a lot about this, but suicide takes more lives than the road toll every year so I thought this was a good opportunity to help raise some money for a worthy cause."
The national final is on May 20 at the New Zealand Hot Sauce Festival being held at the Sweatshop Brew Kitchen in Auckland.
