NASC Assessment NZ: What to Expect and How to Prepare

Your parent's GP says they need more support at home. A hospital social worker mentions residential care. In both cases, the next step is the same: a NASC assessment. No publicly funded health or disability support services in New Zealand — not home help, not respite care, not rest home placement — can be accessed without one.

NASC stands for Needs Assessment and Service Coordination. These are regional teams of health professionals (nurses, social workers, occupational therapists) who assess an older person's needs and coordinate access to funded services. The assessment is free, but the process is often confusing for families encountering it for the first time.

How to Get a NASC Referral

Referrals come through a GP, hospital discharge team, or community health service. Families can also contact their local NASC provider directly — the Ministry of Health maintains a list of providers by region. Once referred, the NASC team schedules an in-person assessment, usually at the parent's home.

Wait times vary by region and urgency. Urgent referrals from hospital discharge teams are prioritised; routine community referrals can take two to four weeks.

What the interRAI Assessment Covers

The assessment uses the standardised interRAI tool — an internationally validated clinical framework used across New Zealand's health system. A registered health practitioner (typically a nurse or social worker) conducts the evaluation, which takes up to three hours.

The interRAI assessment evaluates:

• Physical function — mobility, falls history, ability to manage daily tasks (bathing, dressing, eating, toileting)
• Cognitive function — memory, decision-making ability, orientation to time and place
• Medical conditions — diagnoses, medications, pain management, skin integrity
• Behavioural patterns — mood, anxiety, wandering, aggression, sleep disturbance
• Social and living environment — isolation, caregiver availability, home safety, transport access
• Nutritional status — weight changes, appetite, ability to prepare meals

The assessment produces a formal level-of-care determination: low, medium, high, or very high. This classification drives what services are funded and, critically, whether the parent qualifies for residential care placement.

How to Prepare

The assessment captures a snapshot of your parent's current functioning. Families can help ensure an accurate picture by:

Documenting specific incidents. Falls, medication errors, unsafe cooking episodes, wandering, or confusion episodes — write down dates, times, and what happened. The assessor relies heavily on reported history.

Gathering medical records. A current medication list, recent GP notes, and any specialist reports help the assessor understand the clinical picture. Hospital discharge summaries are particularly useful if the referral follows an admission.

Being honest about good days and bad days. Parents often present better during a formal assessment than they do day-to-day. If your parent has significant fluctuations — lucid mornings but confused evenings, for example — make sure the assessor knows.

Having a family member present. The parent's perspective matters, but an adult child who sees the daily reality can provide context the parent may minimise or forget to mention.

What Happens After the Assessment

The NASC coordinator uses the interRAI results to recommend services. These range from home-based support (personal care, household help) through to residential care placement. The recommendation doesn't guarantee funding — for residential care, a separate financial means assessment through Work and Income determines whether the parent qualifies for the Residential Care Subsidy.

If the NASC assessment recommends residential care, the parent (or their attorney under an activated EPA) must sign an Admission Agreement with the chosen facility. If the admission is urgent, this agreement must be signed within 10 working days.

Families who disagree with the NASC assessment outcome can request a reassessment or lodge a complaint through the Health and Disability Commissioner.

Reassessment and Ongoing Reviews

A NASC assessment isn't permanent. If a parent's condition changes — whether they deteriorate or improve — a reassessment can be requested at any time. The NASC team also conducts periodic reviews to check whether the current level of support matches the parent's evolving needs.

Deterioration triggers are common: a parent assessed as needing home-based support who then has a fall, a hospitalisation, or a significant cognitive decline may be reassessed and recommended for residential care. Conversely, a parent recovering from a stroke may have their support level reduced as they regain independence.

For families, the practical implication is that the first NASC assessment often isn't the last. Keeping detailed records of incidents, changes in functioning, and caregiver observations helps ensure each reassessment accurately reflects the parent's current state rather than a snapshot from a single good (or bad) day.

The Legal Authority Question

If your parent lacks mental capacity at the time of the NASC assessment, someone needs legal authority to participate in care decisions, sign forms, and provide the financial information needed for the means test. An activated Enduring Power of Attorney covers this. Without one, the family faces a four-to-eight-month Family Court process to get property management and welfare guardian orders — during which care decisions stall.

Our Enduring Power of Attorney in New Zealand guide walks families through the full EPA setup and activation process, including how to coordinate with NASC and the residential care subsidy application.
