Travelling first time to the US via Auckland with Air NZ from Sydney. We will be in transit in AUckland airport from about 8-10pm enroute to LA. I have 2 teenagers with me that have some NZ$ spending money and are wanting to know whether there are any shops open in the transit area. E.g. Newsagency??so they can "spend" their NZ$ that have been given to them as a gift. Any help would be appreciated.
