In New Zealand, all applications to assess international specialist qualifications must be submitted to the Medical Council of New Zealand (MCNZ).
If an application is accepted, the MCNZ will work with the Australian and New Zealand College of Anaesthetists who will evaluate the ability of a specialist to practice as an unsupervised specialised anaesthetist at a standard comparable to that required of a Fellow of the College. Therefore, your first step is to contact MCNZ.
The College also provides information on their website. Learn more at ANZCA.
