The Aotearoa Legalise Cannabis Party is welcoming support from the Libertarianz and former ACT party members and will discuss closer co-operation with them at this weekend's party conference.
"Former ACT leader Don Brash represented the views of a large number of ACT constituents when he said personal use of cannabis should not be a crime," party leader Michael Appleby said.
"Now those people in ACT are dis-illusioned with the prohibitionist mentality of John Banks."
"ALCP is a solid political movement with 16 years of experience and we welcome any new members from other parties."
Appleby said a cannabis industry would generate an economic boom in New Zealand at the same time other countries were heading into recession.
"We agree with Don Brash when he said it was economically unsustainable for police to keep spending $100 million each year fighting a war against cannabis," he said.
"We have plenty of overseas evidence of the commecial viability of medical marijuana, industrial hemp and licenced cannabis cafes."
ALCP will hold their conference at Avon City Backpackers, Christchurch from the 20th to the 21st of October.
