Aim:  Although the adverse health consequences of zinc deficiency are becoming increasingly well known internationally, few studies have investigated zinc status in Australia and New Zealand. The aim of this review was to identify which population groups, if any, in Australia and New Zealand are likely to be at risk of zinc deficiency. Methods:  A literature review was conducted to identify papers on zinc status in Australasia using electronic databases (MEDLINE, BIOSIS Previews, CINAHL, EMBASE, Web of Knowledge, ProQuest and Cochrane Library). Government databases and reference lists from peer‐reviewed journal articles were also accessed. Results:  Thirty‐one Australasian studies that measured dietary zinc intake and/or serum zinc were identified. Many were based on a small number of self‐selected subjects, and did not use the recommended procedures for evaluating the prevalence of inadequate zinc intakes and low serum zinc concentrations. Existing data suggest that at‐risk groups in Australasia are toddlers, adolescents (especially those of Pacific and Aboriginal ethnicities), institutionalised elderly and possibly people with diabetes. Conclusions:  Data on the zinc status of selected population groups in Australasia are limited. Randomised controlled zinc supplementation trials that include the recommended indicators and other clinical outcomes are needed to confirm the existence of zinc‐related health outcomes among the at‐risk groups identified.
