When walking in next time walk up to the high point and then take the ridge which goes over towards the kaipo valley, halfway along the ridge is an established campsite.
Good on you for walking out early as I have bumped into deer on the track even shooting a nice 6 point stag some years back. It's a bit of a walk into the hut but as you've seen there's some awesome country in there.
It's a shame "Stanfeild Whare" no longer exists but the river reclaimed it.

Friwi... are you sure you saw trout in the Kaipo as there's a 50 metre waterfall some distance down river where trout could never get up past it!
