1. Introduction
Whio were surveyed in Kahurangi National Park over the summer of 1999/2000 to establish their abundance and distribution (Studholme 2000). We repeated this survey during January to March 2009 and the results are reported here. There were a few variations driven by weather and river conditions, and was completed in one season unlike the first survey that took two summers. The previous survey found an estimated minimum total of 54 adults (19) pairs in Kahurangi National Park. A total of 52 adults (16 pairs) were located this year. The two-person walking survey technique was used as recommended on all rivers due to its reliability and cost effectiveness.
