ANZ A321 it is
 

Air New Zealand has signed a long term lease agreement with Air Lease Corporation (ALC) for five new Airbus A320neo Family aircraft. The first aircraft, a new A321neo, is scheduled for delivery in August 2017 while the first new A320neo is expected in September 2017. The remaining three aircraft are scheduled to arrive in 2018.

any word on the a320 replacements? more neo's?

That was back on June 2 in Doha in a purchase deal with Airbus as opposed to the lease option above:
The airline said it will buy 13 Airbus A320neo (new engine option) international planes and another A320 to join its domestic fleet. Among the international planes are at least three A321neos.
The first A321neo is due in late 2017 with the remainder of the aircraft delivered at intervals through until 2019.
The additional A320 for the domestic fleet will be delivered early next year.

good stuff.

Not bad for a country of population 4.5 million and located at 'the end of the line'.

could do a lot better?

A state with only 5.4mill running multiple A380 / B777's ....

Huh? At last count I think Air NZ had in the region of 100 aircraft.

It's all about geography and being within 8 hrs of 80% of worlds population amongst other things..

The same state the relies on the support of citizens of other countries to fill the said 380's........just waiting for the music to stop on this one.

Sorry, never had an A380, but multiple 777's, with a number of 787's arriving (one here now) to replace ageing 747 and 767 fleets. Just clarifying.

They are meaning a rather large airline based in Dubai, not AirNZ when it comes to the hundreds of 777s and A380s..

Funny how things can be interpreted differently.

I thought they meant Singapore....not Dubai..
