NZ leader relies on backup plane as official transport prone to breakdowns

New Zealand's Prime Minister Chris Hipkins is leading a trade delegation in China.
The plane that transports the prime minister, an aging Boeing 757 called Betty, is prone to breakdowns.
Officials sent an empty backup plane to ensure Hipkins doesn't get stranded in China.
The twin Royal New Zealand Air Force planes that transport the prime minister are about 30 years old and are due to be replaced by 2030.
Political rivals criticized the situation, and the acting Prime Minister acknowledged the need to update the transportation equipment.
