The New Zealand media portrayed Tánczos primarily as the voice advocating the liberalisation of the cannabis law in New Zealand, although he also actively campaigns against genetic engineering, and in favour of restorative justice. He also has a reputation as New Zealand's first and only Rastafarian MP. His most significant legislative achievement, the Clean Slate Act, conceals non-violent criminal offences if the offender does not re-offend after seven years. His Misuse of Drugs (Hemp) amendment bill led the way for regulation changes to allow hemp growing in New Zealand. He introduced the Waste Minimisation Bill to parliament with a narrow majority but succeeded in building near unanimous support across parliament. He negotiated the establishment of an Independent Prison Ombudsman, and has advocated for a Criminal Cases Review Office to look at miscarriages of justice, and against unsustainable dairy farming. In addition to his political policies, Tánczos also supports open source software, and uses the Ubuntu Linux-based operating system on his computer.
