On 31 May, my relaxing 4 hour transil at Akl evaporated as my flight Qf 3 to Akl was delayed by 3 hours!!.Got onto an earlier flight Qf 145 which gave me 90 mins transit in Akl.
Separate tickets but I checked in online for both flights and had digital BPs for both. I think I was on the ground in Akl for around 90 mins, and used transit security.
From plane to lounge below took me less than 10 minutes

If you are coming off Qf 3 there will be more pax using transit security as they will be heading to Jfk so transit security will take a little longer but you wont have an issue unless your inbound Qf 3 is delayed.
(I did do the online NZ arrivals form in case I had to clear immigration but didn't in the end)
