In the build-up to the big day Jarvie wrote an opinion piece, has been mentoring youth and giving out yellow ribbons to show support for his cause.
"This year I am focused on the stigma around suicide prevention. We have the highest youth suicide rate in the developed world, and I feel it's an issue that's getting swept under the rug."
He said his campaign was about giving a voice to those who were not being heard.
"Even if I don't win I will still campaign for this cause because it does mean a lot to me."
He said the topic of suicide applied to the lesbian, gay, bisexual, transgender (LGBT) community.
"Coming out is hard enough, along with all of the other pressures that people face.
There are a lot of people who just need someone to talk to."
Public voting runs until February 11 when the winner will be announced at The Big Gay Out in Auckland.
