Work will begin this week investigating how more than 5000 people got sick from contaminated water.
Attorney-General Christopher Finlayson revealed further details about the Government inquiry yesterday.
It is one of two investigations into the gastro outbreak with the regional council conducting its own.
The outcomes of these will be widely anticipated - however people will have to wait until March next year until the Government inquiry reports back.
The Government inquiry will be headed by retired Court of Appeal judge, the Honourable Lyn Stevens QC. He is joined by NZQA CEO and former Director-General of Health, Dr Karen Poutasi CNZM, and local government and engineering expert, Anthony Wilson.
