27 Aug - Having sorted through some photos prior to e-mailing to a fellow WPO participant, I came across these reasonable shots from northern New Zealand waters - the upper 2 species are very similar, but I think the bill shape/colour and the nostril length indicate that the upper photo is a Parkinson's (Black) Petrel, and the second photo is a Westland Petrel - both NZ endemics. The lower 2 pictures are of the more widespread Grey-faced Petrel.
