The Ministerial Advisory Group (MAG) on Transnational, Serious and Organised Crime (TSOC) was established by Hon Casey Costello, Minister of Customs and the Associate Minister of Police. The group provided independent, expert advice.

The advisory group provided monthly reports to the Minister with its findings and recommendations on different aspects of New Zealand’s response to organised crime. The group commenced its work in late February 2025 and concluded its work in September 2025.

A key focus of the group was to identify gaps, blockages and vulnerabilities that are hindering an effective response to TSOC. It developed advice and options to make a step change in the way that law enforcement, regulatory agencies, and the private sector work to detect, deter and dismantle organised crime groups in New Zealand.

This review provided advice on strengthening operational practices and government decisions on refreshing the Transnational Organised Crime Strategy 2020 - 2025.

The Transnational, Serious and Organised Crime (TSOC) Strategy and Action Plan 2026 - 2030 was released on 19 December 2025.
