"There are things we could have done better, but we're not corrupt," Jager told Q&A in July.

An OECD report released last week slated New Zealand's efforts to implement a convention on anti-bribery efforts, saying since the nation became a party to the convention in 2001 it hadn't prosecuted any foreign bribery cases, and only four allegations surfaced.
"In July 2013, the SFO opened its second investigation into possible foreign bribery related to a fraud investigation involving a New Zealand company," the OECD report said. "The allegation relates to the payment of bribes over a number of years by the company to officials in an Asian country in order to secure access to markets."
The white-collar crime investigator launched the probe based on a newspaper report, and at the time of the OECD report's publication was still at the investigation stage.
In July, New Zealand Kiwifruit Growers launched an the second part of an inquiry assessing the impact of the Chinese legal action on Zespri's brand to investigate what happened during the under-declaring of customs duties. The findings are expected to be released to growers later this year.
