New Zealand First is being urged to order a stock-take of the country's mental health services if it helps form the next government.
About 300 people are attending the party's annual meeting and election year convention in South Auckland this weekend.
Mental health campaigner Mike King told them the system needed a stock-take so it could be determined which aspects were working well, and which were failing.
"If I am feeling suicidal or I am severely depressed... the onus is on me to get myself to the hospital to get the help that I need - that needs to change," he said during his guest speech.
Mr King said more help was needed, earlier, to help those that were struggling, and political parties needed to put politics aside for the review to be carried out.
"This is not about egos, this is not about me, this is not about [Health Minister] Jonathan Coleman, National, Labour, it's not about New Zealand First.
"It's about all of us being on the same page to provide a better service for all New Zealanders."
A community campaign group released a report in April calling for an independent review of New Zealand's mental health system, as well as an urgent funding increase. It followed the report with an open letter signed by over 12,000 people.
Labour and the Green Party backed the calls for an independent review.
Health Minister Jonathan Coleman at the time rejected the idea, saying the government was already increasing funding for the mental health sector.
New Zealand First leader Winston Peters will deliver his keynote speech at the convention this afternoon.
