I looked it up (using KVS availability tool) and N class seems to be a revenue class for CX and is indeed zeroed out for the flight and date the OP is waitlisted. If I were the OP I'd tell his travel agent to contact CX ASAP to go ahead and pay the difference. If it's not done outside of 7 days he probably won't qualify for that fare anymore and would probably have to pay for a super-expensive full-fare ticket.
