That's the going price ATM. Doing a search for the next couple of weeks returns a couple days at ~$6000 return, the rest are in the $10K-14K range.

NZ does discount their biz class fares, in line with UA and QF (all around $5-6K on sale), but equally matches the high prices in the 10-12K range outside of that. Is QF or UA also worth 10-12K? Almost certainly not. But that's the price some people pay.
