Just ahead of Justice Minister Judith Collins' appearance in Parliament this afternoon, Labour claimed to have evidence that Oravida was receiving preferential treatment from Chinese authorities for its milk imports.
Ms Collins is in Parliament today and tomorrow before taking time out due to the strain of attacks over the Oravida conflict of interest affair.
NZ First Leader Winston Peters last night suggested a Chinese import clearance certificate for Oravida's fresh milk posted on the company's website in late December was linked to Ms Collins' visit to China and dinner with a Chinese border control official a few weeks earlier.
Ms Collins' friend and Oravida managing director Julia Xu had previously asked ministers for their help in tackling Chinese authorities' rigorous new testing regime for milk put in place following the Fonterra botulism scare.
Just before Question Time in Parliament this afternoon, Labour MP Grant Robertson released a list of products that had been denied entry to China and which had been destroyed by border control offiicials. It included milk imported by Guangzhou company Ruimu which it sourced from New Zealand Green Valley Dairies, which also supplies the fresh milk Oravida exports to China.
