We found a mass of fluid filled arms attached to a piece of drift wood (2m long) on the high tide mark. Each arm had a white shell on the end that appears to be made up of five sections, all the shells looked same but were of varying sizes. Each shell has something that looks a little like a filter feeder, tentacles that look feathery, that come out of the shell. There were hundreds of the shells. Anyone know what this is...?

They are barnacles of the family Lepadidae I believe. I can't tell which genus but they are similar to the Lepas we have here on the Pacific coast of the US.

We also saw exactly the same thing on a West coast beach in Auckland today 24th Jan, and I can't seem to find any images until I stumbled across this article.
