Inquiries if its valid route

Jay, if you are a citizen of New Zealand, you should not worry about visa free transit and similar stuff because as a New Zealand citizen you have a right to enter and stay in China absolutely visa free for a period of 15 days.

If you are not a New Zealand citizen and if Beijing is your only stop within China, shorter than 24 hours, you are definitely eligible for 24 hour visa free transit and you do not need any kind of visa.
