We describe eight novel microsatellite loci for the tui, Prosthemadera novaeseelandiae, and the crossamplification of six polymorphic loci developed for the bellbird (Anthornis melanura). Fifty tui samples from Tawharanui Regional Park, New Zealand, were genotyped using the 14 loci described. Numbers of alleles ranged from 3 to 16. Observed and expected heterozygosities ranged between 0.180–0.940 and 0.237–0.878, respectively. There was no evidence of linkage disequilibrium. One locus (Ame-22) significantly deviated from Hardy–Weinberg Equilibrium. This study highlights the benefits of longrepeat microsatellites in minimising scoring errors. These are the first microsatellites to be developed for the tui and also provide potential markers for studying other honeyeaters throughout the Austro-Papuan region.
