Hi Rob and Paul,
Wow – great! Interestingly your bird (at least on the single photo on eremaea) – and here I disagree with you, Martin – has an underwing pattern more similar to the Ulladulla bird than to the Port Stephens and Wollongong birds last year. Would be interesting to see more photos of your bird!
Here some photos of the Wollongong bird (first three), then the Ulladulla bird and then one at Hauraki Gulf NZ (last seven pictures) for comparison:
