The Institution of Professional Engineers New Zealand (IPENZ) is the professional body which represents professional engineers from all disciplines in New Zealand. The terms "engineering profession" and "professional engineer/engineering" are used by the Institution in the broadest possible way, to include all those who use a systematic process of analysis, design/synthesis and implementation, strive to operate in a responsible way, are governed by a code of ethics set by their peers, and engage in continuing professional development to maintain the currency of their competence. The Transactions form part of the Institution's regular publications
