Medication management in NZ aged care — obligations and best practice

Medication management is a critical area of HealthCERT compliance. Here are the key obligations for administration, documentation, error management, and self-administration in NZ aged care.

📋 NZS 8134:2021 Health and Disability Services Standards — HealthCERT requirement

Who can administer medication?

Medicines Act 1981 + facility policy

Registered nurses (RNs) and enrolled nurses (ENs) can administer all medications. Healthcare assistants (HCAs) may administer medications only where:

  • The facility has a documented competency-based delegation policy
  • The HCA has been assessed as competent for the specific medications delegated
  • An RN has authorised the delegation in writing for that resident
  • The HCA is supervised and supported appropriately

Controlled drugs (morphine, oxycodone, etc.) must be administered by an RN or EN — they cannot be delegated to HCAs.

The five rights of medication administration

Check all five before every administration

  • Right resident — verify identity against the medication chart (name + date of birth)
  • Right medication — confirm the medication name matches the chart exactly
  • Right dose — confirm the dose, including units (mg, ml, mcg)
  • Right route — oral, sublingual, topical, injection, inhalation
  • Right time — correct time and frequency as prescribed

Documentation requirements

Sign immediately after administration — never before

Record the administration in the medication administration record (MAR) immediately after giving the medication. Never sign in advance. Record any refusals, omissions, or variations and document the reason.

For PRN (as-needed) medications, record the indication (reason given), the time, the dose, and the effect when reviewed.

Medication errors — what to do

Immediate steps

  1. Ensure the resident is safe — assess for any immediate adverse effects
  2. Notify the on-duty RN immediately
  3. Contact the prescribing doctor or on-call medical officer
  4. Monitor the resident as directed by the RN/doctor
  5. Complete an incident report before end of shift
  6. Notify family/next of kin as per facility policy (usually within 4 hours)

Never try to conceal a medication error. Early notification enables the right clinical response and protects both the resident and the staff member.

Controlled drugs

Strict requirements under the Misuse of Drugs Act

  • Must be stored in a double-locked cabinet
  • Two nurses must check, count, and sign for every controlled drug transaction
  • A controlled drug register must be maintained with every administration recorded
  • Discrepancies must be reported immediately to the facility manager and investigated
  • Unused controlled drugs must be destroyed in accordance with facility policy, witnessed by two staff members

Self-administration

Residents have the right to self-administer

Under the Code of Rights, residents have the right to manage their own medications if they have capacity to do so safely. Facilities must have a documented self-administration assessment and policy. The assessment must be reviewed regularly and when the resident's condition changes.

Frequently asked questions

Can an HCA crush tablets?
Crushing tablets changes the form of the medication and may alter its effects — some medications must never be crushed (e.g. slow-release, enteric-coated). This must be specifically authorised by the prescriber and documented on the medication chart. An HCA should never crush a tablet without explicit RN direction and prescriber authorisation.
What do I do if a resident refuses their medication?
Respect the refusal — residents have the right to refuse treatment under the Code of Rights. Document the refusal on the MAR, note the reason if given, and notify the RN. The RN will advise whether to notify the doctor and family. Never force or trick a resident into taking medication.
How long must medication records be kept?
Health records must be kept for at least 10 years for adult patients in NZ. Controlled drug registers have their own retention requirements — check with your DHB or PHO for specific guidance.
What is a standing order?
A standing order is a written instruction from a prescriber authorising specified healthcare workers to administer specified medicines to a class of patients without a patient-specific prescription. They are commonly used in aged care for pain relief, laxatives, and common supplements. They must be signed by an authorised prescriber and reviewed regularly.
