Re visitors visa for Beijing

Hi, I am intending to visit Beijing as a tourist soon, I live in the Bay of Plenty (Tauranga) which office do I go to if I want to do the express visa? I think it would normally be Wellington but I cannot contact that office and know it was damaged in the earthquake. Can you let me know if it is alright to go to the Auckland office or is there an office in Hamilton?
