I am a New Zealand citizen wishing to transit through SZX without leaving the airport. I am seeking clarification on whether I will need a transit visa to proceed with this plan. I am flying from Auckland to Shenzhen then onward to Jakarta, hopefully with only a few hours (less than 5) layover.

I have found this site, which states Shenzhen is implementing a 72-hour TWOV.

But when I look at Timatic, it seems to state no TWOV is possible at SZX. Just to clarify, I don't want to leave the airport, and my layover will only be a few hours.
