The EPMU represented workers in eleven industries, including:

• Engineering
• Print & Media
• Manufacturing
• Telecommunications

The EPMU had 40,000 members and was affiliated with the New Zealand Council of Trade Unions and the New Zealand Labour Party. It was also an affiliate of the International Federation of Journalists. In October 2015, it merged with the Service & Food Workers Union to form E tū.
