New stone.... Nilsenite?

Has anyone heard anything about this stone . Nilsenite . ???(not
completely sure of correct spelling)

I have heard it has been recently discovered on the north shore of
Auckland New Zealand . Apparently it is pinkish in colour and quite
dense , and when cut seems to develop a red tint . I`m not sure of
any other qualities . It might be some kind of Pyrate. Does anyone
know anything about the authenticity of this discovery ? .

Thank you for your help
