Evidence on how Havelock North's water became contaminated will be heard at the next hearing for the Government Inquiry into the gastro outbreak.
After an initial public hearing last week, progress is being made on the inquiry into August's widespread gastro outbreak, when E.coli in the Havelock North water supply caused about 5200 people to become ill.
The inquiry, expected to report back by the end of March, will explore the outbreak's cause, the responses to it and how to prevent such instances in future.
Thursday's public hearing was about process, and "getting the show on the road". At the next hearing - scheduled for November 28 - evidence will be submitted from interested parties, on a number of issues set out by the inquiry.
A second minute released by the inquiry this week has laid out procedural matters discussed at the first hearing, including who would be designated as core participants in the inquiry.
