Is NZ Post Book a courier down? I only get Aramex as an option, but don't want to use them. Is anyone else experiencing this? Thanks :)

Hi :) I have several old pick up addresses when I go to book a courier for pick up via TM, I am wanting to delete some. I can't seem to find how to do this? It gives me an option to add a new address but not delete any of the old ones.... can anyone help? Thanks so much!  Karyn
