Air New Zealand Air Points - Seat Map for NZ Flights not working anymore?

I was just checking out with several tools (KVS, expertflyer) the status of my booking on a SFO-AKL and AKL-NRT leg. There I recognised that the seat mask for C-Class in 744 and 777 is not working anymore, as all 'Premium" reserved seats are shown an not occupied. Is the system not working correctly or did NZ delete all seat reservations?
