PRAG-BEJING-CHENGDU-AUCKLAND(NZ)

I am a Finnish citizen and I am flying from Prag to China on the 6th of dec, arriving in Bejing. I will be in bejing until the 10th, flying to New Zealand. I am worried if i apply for a transit visa because I have a stopover in Chengdu, to switch flight. I arrive in Chengdu at 23.45 on the 10th and will leave at 1.45 AM with my flight to NZ, and will not exit the airport there. Will Chengdu spoil my chances to apply for a free transit?
