Emirates to New Zealand

Hi All,
Sorry for the fairly stupid questions. Due to personal reasons I haven't flown as a passenger for a very long time (I'm ex cabin crew though!) so really have forgotten what it's like strangely!
I was looking for a few pointers regarding my trip to New Zealand in a few days! I'm flying from Heathrow to Auckland with Emirates.
EK4 - LHR-DXB
EK406 - DXB-MEL-AKL
- When trying to buy an upgrade is it typically cheaper at the airport than online in advance? Could I upgrade on one leg only or would I have to upgrade on all of them. (Agent at EK couldn't help me with this as apparently company have booked tickets through travel agent...)
- When connecting in Dubai is it an airside transit? or do I have to clear customs and re-clear security? Also would my bags be checked all the way to Auckland.
- Do all pax disembark in MEL even if we are continuing to AKL?
- What is customs/immigration like at AKL, the only aisle seats available seem to be right at the back of the A380 and I'm very aware that a whole A380 load will be in front of me in the queues!
Many Thanks,
Steve
