Its hard to get Ramen outside of the main cities in NZ but Auckland seems to have dozens of Japanese restaurants. I had miso ramen and gyoza which was good value, authentic and delicious. In addition to the usual local beers they had a choice of Kirin, Asahi or Sapporo at reasonable prices. Good location right by the train station also.
