Morning, all you seekers of shine.
Not sure if you are aware of the free LiDAR datasets available on the interwebs.
Best bit is you can strip the vegetation off and get true ground surface, unlike aerials.

Limited coverage down south, but West Coast not too shabby and some isolated pockets through to East Coast.
Small snippet here of the head of the large basin to the SE of Mt. Turiwhate behind Hokitika
Enjoy
Reall cool picture without the scrub 
Very cool, could be good for finding historic workings that are obscured by vegetation
Another site https://retrolens.co.nz/ (doesnt work on mobile yet unfortunately) has a selection of old aerial photography. Might be useful for identifying old workings etc that have since been flattened
Thank you very much, something to explore 
That’s pretty cool. Thank you. I can see hours being consumed exploring that.
