The stupid thing is that it will allow me to get to the usual options with NZ Post & Aramex & then when I submit the button I get " The pick up or delivery address needs updating" Usually if the adress is wrong it goes straight to this rather than going to the next stage.

Looks like I will have to go into a NZ Post Shop tomorrow & buy one of their bags as there is a glitch with the adress when "booking a courier".This happened a few years back with another adress but since then I have sent 1000s successfully till tonight.

I'm sure what Janine is doing is correct.I had exactly the same issue with an adress with a PO Box number.Everything was correct according to the NZ website.It was the correct post code,the 5 digit po number was also accepted by the NZ Post website but as soon as I tried to "book a courier" it rejected it.I tried other ways to get it accepted but failed.I have sent hundreds of parcels by "book a courier" with no issues till that PO Box adress.All my other bookings before & after to a PO Box number have been successful.I had to go to my local NZ Postshop to send it.
