MERAS was established in 2002 as a separate but associated organisation of the New Zealand College of Midwives. That is why MERAS members are also members of the College. Around 90% of midwives employed by Te Whatu Ora and Te Whatu Ora funded private maternity units belong to MERAS. MERAS represents members in their employment issues, negotiates Collective Agreements, and supports the professional needs of employed midwives.
