A back up Defence Force 757 aircraft has been sent on Prime Minister Chris Hipkins\\u2019 trip to China due to the aircraft\\u2019s unreliability and likely chances of breaking down.
\\nBoth planes are about 30 years old and in less than a year $33 million has been spent on repairs, on top of the $70 million already spent in the last five years.
\\nThey are both set to be replaced between 2028-2030.
\\nFormer Defence Minister Wayne Mapp told Mike Hosking he\'s not surprised to hear figures like that.
