I can't imagine a lot of people are busting to walk the "Motatapu Track". I put it in quotes because it isn't really a track, even in the loose NZ context, but rather just a roughly sketched route through some high-ish tussocky hills between Wanaka and Arrowtown. It isn't even in the Motatapu valley, only near it.
Sadly, a young Australian woman decided to give it a go. I don't want to add to the poor thing's misfortune so I won't dwell on why or if she should have, or her subsequent situation.
But I suspect that all the publicity this "arduous" track has had will probably lure a good number of NZ trampers to "test themselves" up against its "challenging difficulties".
NZ has so much to offer, this "track" doesn't merit getting onto the front page of anyone's wish list.
But you can decide for yourself.
