It depends on what you need it for, so ask the employer, university or licensing body first. If they want a formal comparison, NZQA's International Qualification Assessment evaluates overseas tertiary and vocational qualifications against New Zealand levels and issues a recognition statement used for immigration, employment and further study. Gather every document before applying: NZQA starts evaluating only when all required evidence has been provided. Regulated professions (doctors, nurses, teachers, engineers, electricians) have their own registration bodies on top of this.
