Pacific children have had consistently evidenced low rates for routine childhood immunisations. Using the Pacific Islands Families: First 2 Years of Life cohort study, we investigated the immunisation rate of Pacific infants residing in New Zealand at 24-months postpartum. Full immunisation was reported for 89% of infants, substantially increased from the 53% found in the 1992 national survey and closer to the New Zealand Ministry of Health's target of 95%. Increased parity and maternal smoking were associated with incomplete child immunisation status. Initiatives to increase immunisation rates amongst Pacific children appear to be succeeding and warrant continuation.
