The Fire Service, St John, Surf Life Saving and the RSA have revealed plans for National Volunteer Week.
Internal Affairs Minister Peter Dunne is heading to the Chatham Islands later in the week to speak to the local volunteer fire brigade.
He plans to discuss the upcoming merger of rural and urban fire services, which the government says will "address gaps in rural fire services" and "provide better support for fire service volunteers".
Mr Dunne said the new merged organisation, Fire and Emergency New Zealand, will "keep the local identity of volunteer brigades, and keep local leadership roles".
St John has acknowledged its volunteers, who provide an estimated $30 million of value to the organisation.
