My 10cents worth.Blast straight up to Totara Flats from Walls Whare.Ford the lower flats to the T.L. and stay @ Sayers Hut approx opposite DOC Totara Flats Hut.Probably not officially marked on current topo maps.Then just stalk the valley floor on that side in the last 1 hour shootable light in evening either up or down stream depending on catabatic movement on dusk.Ditto for a morning shot.Once suns up sidle thru the damp supplejack guts say 3-500 mtr contour where they are chewing their cud til noon.Spend the rest of the day fishing/sun bathing.Good luck from an ex NZFS hunter who shot that block a while ago.Regardless a good spot is always a good spot
