MPs’ arguments for and against the bill

Why support it
  • Supporters argued that joining the Budapest Convention lets New Zealand cooperate with other countries to investigate and prosecute cyber-crime, much of which originates outside the country's borders.
  • Supporters said the bill gives law enforcement new tools, such as preservation directions to stop evidence being deleted, and expanded mutual assistance for gathering digital evidence stored overseas.
  • Supporters noted the measure responds to growing financial and emotional harm from cyber-crime and implements a recommendation of the royal commission into the March 15 terrorist attacks.
Why oppose it
  • Opponents raised concern that the legislation could enable cooperation with foreign governments in ways that might affect refugees, political dissidents, or people engaged in lawful protest.
  • Opponents pointed to the narrowing of the political offence exception, arguing individuals could be subject to surveillance or data preservation because their country of origin is a treaty partner even where the conduct relates to peaceful political activity.
  • Opponents questioned safeguards around judicial oversight, proportionality, and dual criminality in the bill's enforcement powers.

Full bill summary & link to official bill page

This bill changes New Zealand law so the country can join the Council of Europe's Convention on Cybercrime, the Budapest Convention — the leading international treaty for cooperating against online crime. It creates or updates powers to rapidly preserve electronic evidence (such as stored computer data that could otherwise be deleted), obtain data through production orders, and share evidence and requests with overseas authorities. It amends statutes covering search, surveillance, mutual legal assistance and extradition, affecting police, prosecutors and businesses that hold digital data.

Accession puts New Zealand alongside dozens of countries in a shared framework for investigating cybercrime and cross-border digital evidence. Supporters argue crime is increasingly online and borderless, so faster preservation powers and international cooperation are needed to catch offenders and help victims of hacking, fraud and online abuse. Critics raise privacy and civil-liberties concerns about expanded preservation and data-sharing powers, worry about oversight and the risk of assisting countries with weaker rights protections, and question safeguards on how broadly the new powers can be used.
