Some authorities recognise the SIPO as a subspecies of the European Oystercatcher (H. ostralegus finschi). Most lists don't accept this (the distribution is incredibly disjunct), but it still gets used. Interestingly, some lists also have the Chatham Oystercatcher as a race of the Variable Oystercatcher. Regarding common names, I assume NZ has an official list of common names, and whether this differs from the field guides I am not certain. However, NZ doesn't seem to have done what Birds Australia tried to do and get internationally accepted names used in this country. Hence, most cormorants are still Shags, smaller albatrosses are Mollymawks, etc. The Red-billed Gull is slightly different in that some authorities accept as a separate species from the Silver Gull (rather than a subspecies) and Red-billed Gull would be the accepted name. This would distinguish it from the Black-billed Gull.
Anyway, Scientific Names are the important one to look at.

Hi all, Just got a copy of The hand guide to the birds of New Zealand. Its list of oystercatchers are as follows

Pied Oystercatcher - Haematopus ostralegus ( a totally differant bird to the one we find in Australia - Haematopus longirostris???)

Chatham Island Oystercatcher -  Haematopus chathamensis

Variable Oystercatcher - Haematopus unicolor

There was no mention of the South Island Oystercatcher - Haematopus finschi. Is it a recent new species? The book says it was published in 2001! Also the book seems to use alot of names for birds that are more like slang or just plain uncommon or ambiguous ( example above with Pied Oystercatcher ) than official english names and I'm not talking about names like Kakpo or kea, I'm talking about Red billed gull for Silver gull and Pied Shag for Pied Cormorant and even Black Browed Mollymawk for Black Browed Albatross! Any thoughts on what some of you might think is a trival matter? my appologies if you do
many thanks in advance
