Eudyptes robustus breeds on the Snares Islands (3 km2), 200 km south of New Zealand. The population was estimated at 23,250 breeding pairs in 1985-1986; 19,000 on North-East Island, 3,500 on Broughton and 750 on the Western Chain islets. In 2000, 25,861 pairs were counted on North-East Island and 4,000 on Broughton (Amey et al. 2001). The 2008 survey produced counts of 21,819 nests on North-East Island and 4,234 nests on Broughton, suggesting that the species had experienced a poor breeding year in line with that observed in the other seabird species present; a repeat survey in 2010 found 25,905 nests on North-East Island and 5,161 nests on Broughton (J. Hiscock in litt. 2012). The population is considered stable (J. Hiscock in litt. 2012). The wintering range is largely unknown, although occasional records from the waters off Tasmania and South Australia suggest a movement towards Australia (D. Houston in litt. 2008).
