I think with this particular event the most up to date and informative news seems to be coming directly from NZ. Everything else seems to be confused and lacks in some fact. Which is the norm after something like this i guess. Visit the nzherald.co.nz for what seems to me to be the most up-to-date news. We also have to remember that details are still emerging...
It sounds to me like something went very wrong, and on speaking to my partner (who flies these aircraft in NZ) he too has said he would not like to speculate and would prefer to hear the outcome of the flight deck recorder.
