This locality has produced a diverse field of Baryte. This is one of the most unusual with long and thick bladed crystals. They are a bit like Northumberland, England Barytes in that the color and forms are a little alike. The better side shows  light blue translucent crystals while the flip side is more opaque and tan. There is some manganese oxide spots on the opaque sides. Each crystal is pristine and terminated perfectly.  Overall a very nice specimen, just unusual.

This mine was once featured in a Mineraolgical Record issue V6 n1, 1975 titled Minerals of the Tui Mine, New Zealand". The specimen comes with an old Willard L. Roberts collection label in which he states it is from the author of that article, Dr. R. L. Ansin. The mine ceased operations in 1973, and shortly thereafter mineral collectors moved in for the goodies. They pulled out not only nice Cerussite like this, but also Azurite, Gold, Smithsonite, Chalcopyrite etc. This specimen contains one large 3cm vug filled with jackstraw white, long and slender white Cerussite crystals to 8mm. There are little, less than 0.5mm, faint blue Dundasite spheroidal groups covering much of the matrix along with the Cerussite.
