As of last night there were 15 parties who indicated their interest in being involved in proceedings under this act, from national bodies - such as Crown Law on behalf of the Ministry of Health, Ministry for the Environment, and Department of Internal Affairs - to local residents.
Most requested to be designated as a core participant - including Hastings District Council, Hawke's Bay Regional Council, Hawke's Bay District Health Board, Local Government New Zealand, and Water New Zealand.
MWH New Zealand Ltd, which has a services agreement with the district council, also requested to be designated as a core participant. They have provided the council with engineering services (excluding specialist projects) for water services, roads, solid waste, and other services since 2001.
Several parties indicated their interest in the inquiry but did not specifically askto be designated as a core participant.
This included the Plumbers, Gasfitters and Drainlayers Board, Green MP Catherine Delahunty, Transparent Hawke's Bay, the Choose Clean Water Group, and a local resident.
Matthew Nolan, the founder and director of web-based emergency preparedness network Readynet, also wished to be heard by the inquiry.
The inquiry would note the parties who wish to be designated as "core participants" and would release its decision on this shortly after the initial hearing.
Also to be discussed tomorrow will be whether to conduct the inquiry in two stages.
Stage 1 would cover the cause(s) of the outbreak, whether any person or organisation was at fault, the adequacy of drinking water supply management for Havelock North, and the preparedness and responses of local and central government agencies and any other relevant parties.
Stage 2 would cover systemic matters and possible changes needed for the future.
The public hearing will be held at 10am tomorrow at Hastings District Court, 106 Eastbourne St West, Hastings.
