2.6 Submissions and hearings
The Royal Commission advertised, calling for expressions of interest, in newspapers throughout New Zealand. Notices were placed in four major metropolitan papers – the New Zealand Herald, Dominion Post, The Press and Otago Daily Times – in their 2 July 2011 editions, and again in The Press and Dominion Post on 13 July 2011. In addition, notices were placed in the following regional daily newspapers on 6 July 2011: Northern Advocate, Bay of Plenty Times, Waikato Times, Gisborne Herald, Wanganui Chronicle, Taranaki Daily News, Manawatu Standard, Hawke’s Bay Today, Nelson Mail, Timaru Herald, Southland Times and Greymouth Star and in the Marlborough Express and Hokitika Guardian on 4 July 2011. People or organisations were invited to meet with the Royal Commission, provide a written submission, participate in public hearings or communicate information to the Royal Commission. The Royal Commission received 80 expressions of interest from interested parties advising that they wished to make submissions. Those advising their intent to make a submission include people who were trapped in buildings as a result of the 22 February 2011 earthquake, building owners and tenants, persons with professional knowledge about matters arising in the Inquiry, learned societies, Auckland Council, the Christchurch and Wellington City Councils, Local Government New Zealand and the Department of Building and Housing.
Public hearings are being scheduled on an issue-by-issue basis. As set out in table 1, the hearings will commence on 17 October 2011. It is not possible to say when they will be concluded, because of the uncertainty about completion of the DBH’s technical investigation.
People wishing to give evidence and/or make submissions will be required to provide them in advance of the hearings. The Royal Commission is asking that this be done in electronic form, to facilitate publication of the material in advance on the Royal Commission’s website, thereby giving notice to other interested parties and the public of what is intended to be said. The Royal Commission will follow this approach in all cases, unless there are compelling reasons for a different approach, to ensure the effectiveness of the Inquiry. Public hearings will be streamed live via the Internet.
Advice received by the Royal Commission from those whom it has asked to provide it will be referred to in the hearings. The hearings will also provide an opportunity for parties with relevant evidence to provide it and be questioned. They include those who have filed expressions of interest and those whom the Royal Commission has itself identified as likely to have information that will assist the Royal Commission in carrying out its task.
The information considered will also include relevant evidence obtained and called by counsel assisting the Royal Commission.
2.7 Counsel assisting
Counsel assisting have a duty to ensure that the Royal Commission has the evidence and information it needs to fulfil its obligations under the Terms of Reference. Initially two counsel assisting the Royal Commission were appointed, Stephen Mills QC and Mark Zarifeh. In mid-August, Marcus Elliott was appointed as a third counsel assisting the Royal Commission, with a specific focus on representing the interests of those bereaved and injured in the February earthquake.
2.8 Meetings with families
The Royal Commission’s chairperson and members of the Royal Commission’s staff have been meeting with families who lost relatives in the February earthquake since the beginning of July. Most of these meetings have been with individual families, but some group meetings have also been held. The Royal Commission has appointed a Family and Community Liaison Officer. Her role includes responding to enquiries from families both New Zealand and overseas-based, and keeping them informed about reports being published and the Royal Commission’s progress in general, with updates by email and post.
In the week beginning 29 August, the Family and Community Liaison Officer attended the Coroner’s inquests and liaised with families, providing them with information about the Royal Commission, answering questions and offering support. The Family and Community Liaison Officer is working closely with the Senior Communications Advisor for the Royal Commission to ensure that families receive communications in a timely way and are advised of new information before it is released to the media.
2.9 Staffing of the Royal Commission
The Royal Commission is now fully staffed, including the executive director, a project manager, a senior communications advisor, senior policy analysts, information managers, hearings planner and administration team. Additional administrative support is provided to the Royal Commission by the Department of Internal Affairs.
