Passport validity??

Hi,My husband has just got his blue card from the company to work in Macau and has I have my visa under him as his spouse. However, I was just wanting to double check, we are leaving at the end of February 2014 but my passport expires in September 2014, giving me just over 6 months validity on my passport. Would this be ok? I have a NZ passport and was thinking of renewing it later this year in June 2014 as now I don't have enough time to do so.
