Some interesting reading was put out last year regarding this, NASO / Health NZ requested “industry” feedback regarding Rotary and FW platform preference (H145 for majority of standard operators and H175 / AW169 for those requiring larger platforms Auckland / Northland etc).
They also asked for feedback on crew composition, who medical staff should be employed by etc.
Pretty sure (not 100%) most operators should have H145’s by 4th quarter 2026 or early 2027.
