mining prospects in nz, page-2

While I like the BTU story and have been invested here before, one issues continues to haunt me ... why do NZ investors only hold 8% of this stock. Given 1) the lack of decent resource names on the NZX, 2) the highly prospective nature of this resource and 3) the recent opportunity to buy "cheap" post some forced selling from a couple of aussie funds, the NZ holdings have remained surprisingly low at 8%. And of this 8%, there are very few institutional holders I have been told. Do the NZers know something about the approval process that we don't??
