"Since annual exports to China fell from their peak in 2014, exports to China and Australia have been around $8.4 billion each. Annual exports to Australia peaked in January 2012 but have been generally falling since, due to lower crude oil exports," Statistics NZ international statistics senior manager Jason Attewell said.
