interRAI implementation timeline

We worked with experts across the aged care sector to achieve full implementation of interRAI in 2015. The timeline for the implementation project is below.



The New Zealand Best Practice Guidelines – Assessment Processes for Older People identified interRAI assessments as the best assessment instruments to meet the objectives in the 2002 Health of Older People Strategy.


Five District Health Boards (DHBs) pilot the interRAI home care assessment to identify implementation requirements. A key finding is the importance of consistent training.


All DHB Chief Executives support national implementation of the interRAI assessments for home and community.


Start of the interRAI National DHB Implementation Project (2008-2012). Implementation is phased and DHBs take individual responsibility for implementation – subject to agreed national criteria.


DHBs, in conjunction with the New Zealand Aged Care Association, agree to support a project, to run from 2011 until 2015, to voluntarily introduce interRAI assessments in Aged Residential Care.


All DHBs are using interRAI for assessing older people’s support needs for home and community support services.

Associate Minister of Health announces that interRAI would become the mandatory assessment instrument for all Aged Residential Care providers from July 2015. New Zealand is now the first country in the world to have use of these home and community, and residential care tools nationwide.


The Central Region’s Technical Advisory Service (TAS) becomes the national service provider for interRAI in New Zealand, and the interRAI Services business group is created within TAS.


The Palliative Care assessment is introduced as an alternative for home care assessors to be used with clients living in the community and with a terminal condition or prognosis.
