Engineering New Zealand (ENZ; previously the New Zealand Institution of Engineers – NZIE and then Institution of Professional Engineers New Zealand – IPENZ) is a not-for-profit professional body that promotes the integrity and interests of members, the profession, and the industry. It seeks to "bring engineering to life" and has more than 20,000 members.

The organisation's strategy is to deliver greater credibility, recognition, influence and connection for members. It promotes engineering as a career and advocates on behalf of members. Engineering New Zealand sets standards and performs assessments that meet international standards for Chartered Memberships and Registrations for Chartered Professional Engineers. Regional branches run networking events, while technical groups help members stay up-to-date on specific areas of expertise. Members can access continuing professional development and gain experience as volunteers by serving on committees and other bodies.

All members of Engineering New Zealand commit every year to follow the organisation's Code of Ethical Conduct, and to carrying out continuing professional development.
