Is this you? I'm just reading about it:
The tramping route has been highlighted as one of the most dangerous, both in New Zealand and worldwide, due to the hazardous alpine nature of the track.[3][4][5] The route is maintained by the Department of Conservation, who recommend it is best attempted by experienced trampers.[1] A 2014 proposal to install safety rails was not adopted, partly so as not to encourage attempts by less-experienced hikers.[6]
I think I'll just look at the pictures.
