Air New Zealand Air Points - Are Sky couches or new premium economy being rolled out to HKG - AUCK route this year

I am considering making a premium economy booking for Dec 2012 HKG - Auckland - HKG but would obviously prefer it if the PE seats were the new version or perhaps even sky couches would work best for us....does anyone have any idea of roll out plans and timings?
We will be 2 adults and 3 children travelling - which seats should i get my TA to request assuming flights will be on existing metal!
Thanks

Unlikely, the project is on hold although they may start by the end of 2012
