Unfortunately the NZRBN list
has not been kept up to date so there are a number of species, and taxonomy changes, that are missing. A new NZ checklist was produced last year: "Checklist Committee 2010. Checklist of the Birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th ed. Wellington, Te Papa Press". We haven't been able to get a copy of this list electronically. If anyone is able to get this, or even do a tedious comparison of the book with the "old" online version we could update the BUBO listing version.
