it does look honeycreeper-like in this photo because there is no sense of scale, but huia were large birds. The only surviving NZ wattlebirds are the saddlebacks (two subspecies or two full species, depending on which author you choose to follow) and the kokako (again two subspecies or two full species, although that of the South Island is now officially extinct).
I haven't heard of any for a fair while. There's circumstantial evidence the species may have survived for longer than the official extinction date (1907) but only a few decades if that. I can't give much credence to any sightings after the 1950s or '60s.
