I should have worded my previous post better!
In my opinion. The fact that a climb occurred during an approach is "unusual" so the fact the aircraft was 1000 ft below where it should be IS an issue.
I have no experience of operations into NZQN.
However, my concern is how can two pilots allow an airliner to be in a position that it shouldn't. Furthermore, if procedural errors can ocurr like this then what guarantees are there that similar errors don't ocurr elsewhere.
After all. Wasn't one of the reasons for grounding tiger the following events:
1. The aircraft not being where it should have been after a go around in Avalon.
&
2. Another aircraft being BELOW the procedural height it should have been on approach to Tullamarine.
