The inquiry had considered but rejected setting up advisory panels, preferring instead to ‘‘engage directly and widely’’ Prof Paterson said.
‘‘Listening well to a wide range of communities and stakeholders is important for our inquiry,’’ he said in an email to stakeholders.
‘‘The panel members want to hear from everyone, including service users, their families/whanau, service providers, advocates, sector groups, and experts.
‘‘We want to hear all ideas, big or small, specific or broad, innovative or building on what’s already happening.’’
A consultation document will soon be released, along with web-based audio and video recordings,
People can already submit to the inquiry via email.
