Here are two photos of an animal I have seen only once. I have identified it as Plocamopherus imperialis. We found it on a night dive at the Poor Knights Island, northeastern New Zealand. Both photos are mine. A friend of mine claims to have seen one in Whangarei Harbour on a night dive.

They are certainly more brightly coloured than southeastern Australian animals but the traces of small brown spotting in your photos and the large bulbous papillae, confirm they are Plocamopherus imperialis. They are apparently a rare visitor to New Zealand.
