Marrying my Chinese wife in New Zealand and travel to China.

Hi there,

My name is Alex and at the end of November 2016 I will marry my wife in NZ and I want to go to China with her to visit her family and spend Christmas and New Year, (but do I need to be married with her for sometimes before I apply for a Chinese visa "for example few months" or once I got married than I should apply for it straight away at the same day and provide marriage certificate to embassy).

Please if you can give me some advice because I tried to call and ask Embassy but the line is always busy or they do not pick up the phone, thank you so much for your advice and time.
