South side of V-notch holds snow late in the year.

Climb the spur just upriver of the creek draining V-notch pass, and once on a good terrace sidle to the base of the tussock/screen face leading to the pass. Climb to the pass, wither crossing at the V-notch, or (as I did) some 20m east of it.

Once on the southern face it is possible to sidle on good steady scree below pt2058 to reach the Ahiriri-Temple pass.

Alternatively descend the gully below the V-notch into the head of the Ahuriri.

Note: Described in the reverse direction to your journey

Sidling north from the Temple-Ahuriri pass, dropping slightly as you go leads across stable screen faces below pt 2058 to the ridge just east of V-Notch pass. Drop to the pass staying on scree south of the summit rocks - I crossed some 20m east of the V notch itself.

Drop into the head basin. The creek becomes impassable, so sidle west onto good open tussock spurs. The eastern valleyside is also passable but very scrubby lower down - I don't recommend the experience.
