Amendments to New Zealand’s monetary policy framework came into effect on 1st April 2019. The remit, charter and code of conduct are key components of the new framework. The remit provides the Monetary Policy Committee (MPC) with its operational objectives, consistent with the economic objectives in Section 8 of the Reserve Bank of New Zealand Act (1989). The MPC will also be bound by the MPC charter and code of conduct. The charter provides directions on decision making procedures, transparency and accountability. The code of conduct sets out minimum standards of ethical and professional conduct that must be adhered to by members of the MPC.
