The Government has announced the terms of reference for its inquiry into the Fonterra food scare.
The first part of the inquiry will look into how the potentially contaminated whey protein entered the domestic and export markets and how that was subsequently addressed.
It will use information from the Ministry for Primary Industry's compliance investigation and should be completed before Christmas.
The inquiry will also look at the regulatory and best-practice food safety requirements and whether they are adequate.
Food Safety minister Nikki Kaye says it will be a robust, independent inquiry into the cause of the incident, and the response to it.
Two newly-appointed members will work with the inquiry's chair, Miriam Dean.
They are a director of Food Standards Australia New Zealand, Tony Nowell and a former chief executive of a dairy food safety authority in Australia, Anne Astin.
