It will, especially since a lot of the proposed fast-track mines seem to be in high-value tourism areas such as the Coromandel (there's a proposed mine right near Cathedral Cove FFS).

For a nation to go along with this feels like self harm. Mining revenue is way more likely to all wind up offshore. Also tourism is theoretically infinite if it's managed properly whereas mining is finite.

Another factor is some of these proposed mines treat infrastructure load as an externality so there are a bunch of hidden costs to ratepayers/taxpayers.
