在新西兰
刚去查了移民局网站：http://www.immigration.govt.nz/migrant/stream/visit/visitors/
上面是这样写的：
How long can I stay?
The maximum stay under a visitor visa is usually nine months in an 18-month period.
To work this out, we:
- look at the last day that you intend to be in New Zealand (eg 1 July 2012)
- count back 18 months from that date (eg 1 January 2011)
- check that you will not be spending more than nine months in New Zealand during this time (eg 1 January 2011 to 1 July 2012).
If you are a visitor from a visa-waiver country, you apply for a visa when you arrive by filling in an arrival card. You will still need to meet standard health and character requirements but this will be done with a declaration on your arrival card.
You will be allowed to stay for three months (or six months if from the United Kingdom) on each visit, and no more than six months in any 12-month period.
To work this out, we:
- look at what date your visit will end (eg 1 July 2012)
- count back 12 months from that date (eg 1 July 2011)
- make sure that in that 12-month period, you will not be spending more than six months in New Zealand (eg 1 July 2011 to 1 July 2012)
然后我又去查了这个Visa-waiver country的list：http://glossary.immigration.govt.nz/VisaFreeCountries.htm
看了好几遍没有CHINA，所以结论就是：两年多次往返（每次入境3个月）这种签证，是按下面酱紫算的！

那举例，如果说签证到今年9月到期，从今年9月往前推算18个月里只要没满9个月就可以继续再来咯？那这18个月之前但又是2年内的那6个月来过的时间就可以不算在内了么？！究竟2年可以在这里一共待多久啊？！
