Medication Management in Aged Care: NZ Compliance Guide (2026)
Medication management in aged care is one of the highest-risk areas for resident safety and regulatory compliance in New Zealand. This guide covers the key legal and standards requirements under the Medicines Act 1981, Nga Paerewa NZS 8134:2021 (Standard 2.7), controlled drug obligations, self-administration policies, error reporting, and pharmacist oversight. All references are current as of May 2026.
1. Legal Framework: Medicines Act 1981 & Regulations
The Medicines Act 1981 and the Medicines Regulations 1984 set the legal foundation for all medicine-related activities in New Zealand. In aged care, this means:
- Only authorised practitioners (doctors, nurse practitioners, designated prescribers) may prescribe medicines.
- Only authorised staff (registered nurses, enrolled nurses under delegation, or authorised care workers) may administer medicines.
- All medicines must be stored securely, with controlled drugs in a locked, fixed cupboard or safe (regulation 46).
- Records of receipt, administration, and disposal must be kept for at least 10 years.
Key Rule: Under section 18 of the Medicines Act 1981, it is an offence to administer a medicine without a valid prescription or standing order. Always check the prescription is current and signed.
2. Nga Paerewa NZS 8134:2021 – Standard 2.7
Standard 2.7 of NZS 8134:2021 specifically addresses medication management. It requires providers to have a documented system that ensures:
- Safe prescribing, dispensing, administration, and review of medicines.
- Residents (or their whānau) are involved in decisions about their medicines.
- Medicines are administered only by staff with current competence.
- There is a process for reporting and learning from medication errors.
Key Rule: Standard 2.7(c) requires that “the provider ensures that the resident’s medication is reviewed at least every six months by a pharmacist or prescriber.” This is a mandatory audit point.
3. Self-Administration Policy
Where a resident is assessed as capable, they may self-administer their own medicines. The policy must include:
- A written assessment of the resident’s cognitive and physical ability (e.g., can they open the bottle? Do they remember to take it?).
- A signed agreement between the resident, family/whānau, and the facility.
- Regular reassessment (at least quarterly or after any change in condition).
- Secure storage of the resident’s own medicines in their room (locked drawer or cupboard).
Warning: If a resident self-administers, the facility is still responsible for monitoring outcomes. If the resident misses doses or makes errors, the self-administration privilege must be withdrawn immediately. Document the decision.
4. Controlled Drugs (CDs)
Controlled drugs (e.g., morphine, oxycodone, midazolam) have additional requirements under the Misuse of Drugs Act 1975 and the Medicines Regulations 1984.
- Storage: Must be in a locked, fixed cupboard or safe within a locked room. Only authorised staff may have access.
- Records: A separate Controlled Drug Register must be kept, recording every receipt, administration, and disposal. Entries must be made in ink, signed, and witnessed.
- Disposal: Unused or expired controlled drugs must be returned to a pharmacy or destroyed by an authorised person (e.g., a pharmacist) with a witness. Record the destruction in the register.
Key Rule: Regulation 46(3) of the Medicines Regulations 1984: “The person in charge of the institution must ensure that a record of every quantity of a controlled drug received, administered, or disposed of is kept in a register.” Auditors will check this register.
5. Medication Error Reporting
Errors must be reported, analysed, and used to improve systems. Under Standard 2.7(e), the provider must have a process for:
- Immediate reporting to the registered nurse or clinical manager.
- Documenting the error (what, when, who, outcome).
- Notifying the prescriber and family/whānau if there is harm or potential harm.
- Conducting a root cause analysis for serious errors (e.g., wrong drug, wrong dose, wrong resident).
- Implementing corrective actions (e.g., retraining, system changes).
Warning: Failure to report a medication error can lead to disciplinary action by the Nursing Council or the Health and Disability Commissioner. It also puts residents at risk. Always report, even if no harm occurred.
6. Pharmacist Oversight
Pharmacists play a critical role in aged care medication safety. Under Standard 2.7, the provider must engage a pharmacist to:
- Conduct six-monthly medication reviews for each resident (as noted above).
- Provide advice on storage, compatibility, and interactions.
- Audit the medication management system at least annually.
- Train staff on new medicines or high-risk drugs.
The pharmacist should have a written agreement with the facility outlining their responsibilities. The review must include a written report that is shared with the resident’s GP and the facility clinical manager.
Key Rule: The six-monthly pharmacist review must be documented in the resident’s clinical record. If the review identifies issues (e.g., unnecessary medicines, dose adjustments), the prescriber must action them within a reasonable timeframe.
7. Practical Tips for Staff
- Always check the 5 Rights: Right resident, right medicine, right dose, right route, right time.
- Use a medication chart that is legible, dated, and signed by the prescriber.
- Never administer a medicine if you are unsure – ask a senior nurse or pharmacist.
- Document immediately after administration. Never pre-sign or backdate.
- Report any discrepancy in stock counts, especially for controlled drugs.

Frequently asked questions
What is the legal requirement for medication storage in aged care?
Under the Medicines Regulations 1984 (regulation 46), all medicines must be stored in a locked cupboard or room. Controlled drugs (e.g., morphine) must be in a locked, fixed cupboard or safe within a locked room. Only authorised staff may have access.
How often must a pharmacist review a resident's medications?
Standard 2.7(c) of NZS 8134:2021 requires that each resident's medication is reviewed by a pharmacist or prescriber at least every six months. The review must be documented in the resident's clinical record.
Can a resident self-administer their own medicines in an aged care facility?
Yes, if they are assessed as capable. The facility must have a written policy, a signed agreement, and regular reassessment (at least quarterly). The facility remains responsible for monitoring outcomes.
What must be recorded in a controlled drug register?
Every receipt, administration, and disposal of a controlled drug must be recorded in ink, signed, and witnessed. The register must include the drug name, strength, quantity, date, time, and the names of the resident and administering staff.
What should I do if I make a medication error?
Report it immediately to the registered nurse or clinical manager. Document the error, notify the prescriber and family if there is harm, and participate in a root cause analysis if required. Never hide an error – it is a safety and compliance risk.
