The entry for this is incorrect. N. vuwaensis is a freshwater polychate - so far only know from a couple of rivers in Fiji . Glasby (on tenuous grounds) tried to synonymise this with N. tiritae from New Zealand freshwaters ignoring differences in the number of peristomial cirri and parapodial characters. He also didn't attempt to explain how a freshwater polychaete could have travelled from Fiji to New Zealand (or vice versa). As the author of the original desciption I'm glad to see it recognized here.
