It's a competition that puts tastebuds, stomach lining and intestinal fortitude to the test.
The New Zealand Chilli Eating Champs national finals will be held on June 25.
Competitors will eat through a menu starting with a jalapeno, then hotter raw chillies, curry and chilli sauce shots before facing up to the world's hottest chilli peppers, including ghost chilli and the Carolina Reaper, inset.
The average supermarket chilli has a Scoville heat measure of 3500-10,000 units, but some of the peppers in the contest measure upwards of 1 million units. The hottest, Carolina Reaper, rates at an average of 1,569,300 heat units.
