Looks like an Black House spider....but we're not in the South Pacific, so not sure what it is?
Hi, welcome to Spider ID. 🙂 You have a Black Lace Weaver (Amaurobius ferox).
Thanks for the reply ItsyBitsy!
I was thinking it was a possibility unity, but the colors seemed off and the design didn’t seem right for it. And the bulbous pelicarps werent so. If. But having looked at other photos, I think you’re right.
