What is interRAI? 

interRAI is the trademark name for the suite of meticulously-researched clinical assessments that build a picture of a person’s health and wellbeing needs. Each assessment provides information to inform clinical decision-making and care planning. 

The interRAI international consortium develops, maintains and reviews assessment instruments using rigorous research standards. They license member countries to use interRAI assessments. The consortium has developed assessment instruments for children, youth and adults, across a broad range of healthcare settings. interRAI Services is licensed to provide six assessments for use in New Zealand. Two more are being evaluated for use in pilot programmes.  

The assessments are: 

  • Contact Assessment: a brief assessment to triage needs and establish a health and wellbeing baseline  
  • Home Care assessment: an in-depth assessment focused on supporting a person at home 
  • Community Health Assessment: a modular in-depth assessment focused on supporting a person at home. Modules (e.g., mental health) can be added as required 
  • Long Term Care Facilities assessment: an assessment for people who live in aged residential care 
  • Acute Care assessment: an assessment used in hospitals, focused on rehabilitation needs  
  • Palliative Care assessment: an assessment used in aged care, hospice care or in the community, focused on palliative care needs. 

Assessments in pilot: 

  • Community Mental Health assessment an in-depth assessment focused on supporting adults with mental health needs. 
  • Check-up Self-Report assessment a brief self-reported assessment completed by adults living in the community.

How we work 

interRAI Services delivers a range of services to support the use of interRAI assessments in New Zealand. 

  • Software: we deliver the Momentum electronic health record platform to assessors. 
  • Education, training and certification: we train health professionals to deliver the assessments and non-health professionals to understand the interRAI assessment outputs. We also accredit educators to deliver interRAI training in their own organisations. 
  • Data and analysis: we work with data gathered through assessments to support research and decision-making. 
  • Programme management and collaboration: we work with colleagues across the health sector to promote and support the use of interRAI assessments. 

Our organisation 

interRAI Services is a business unit within Te Whatu Ora - Health New Zealand. We work in collaboration with IT, Health of Older People and clinical assessment colleagues across the motu to deliver excellence in assessment to health consumers. 

We’re part of the Service Improvement and Innovation team, led by Dr Dale Bramley. 

Oversight is also provided by our governance ecosystem.

interRAI Service Design

In late 2019, the Ministry of Health and TAS jointly commissioned a service design review to identify and evaluate future opportunities for interRAI Services.

Read the executive summary report below.

Service design report - summary version


We're focused on implementing the recommendations made in the report.

Recommendation 2: revise governance and decision making

We have completed the work of revising our governance system. The previous interRAI Governance Board has been replaced with the interRAI Leadership Advisory Board and the interRAI Network, which together make up the interRAI governance ecosystem.

Recommendation 7a: build a culturally appropriate assessment model

A culturally appropriate assessment model (CAAM) has been developed with help from Francis Health (now Deloitte).

Culturally Appropriate Assessment Model

We gathered input from kuia and kaumātua, service providers and other stakeholders to come up with this model. 

Read the CAAM report and recommendations

The CAAM is now being piloted, tested and refined. Watch this website for updates as they happen.
