How to Prepare for a Food Safety Audit in New Zealand

Food safety audit preparation starts with understanding what will be assessed, then checking whether your procedures, records and day-to-day practices tell the same story. A general checklist can organise the work, but it cannot decide the requirements for every food business.

This New Zealand guide is for owners, managers and quality teams preparing for an upcoming verification, customer audit or certification assessment. It explains a practical readiness check and how to brief a focused preparation engagement. The formal assessor still determines the assessment findings and outcome.

Food safety audit preparation: confirm the scope first

Start with the assessment invitation, current registration or system documents, and the previous report. Confirm the date, site or sites, activities and products covered. Identify the criteria and the person or organisation conducting the assessment. If something has changed since the last visit, explain that change rather than assuming the earlier scope still fits.

MPI’s guidance on getting a food business verified explains that verification checks depend on what the business does and the plan or programme it operates under. A preparation list therefore needs to fit the actual operation.

These are starting points for a discussion, not a classification decision or a complete checklist for each regime. For other registered programmes or industry requirements, identify the actual requirements before adapting this approach.

ISO’s explanation of certification describes an independent body providing written assurance against specified requirements. Keep the readiness engagement and the formal assessment roles clear, including any applicable recognition, scope and independence conditions.

Choose records that show how the business operates

Use the applicable plan, programme, standard and assessment instructions to identify the records needed. Then check that current versions are accessible and that completed records make sense alongside the procedures they support. An empty form shows the form’s design; it does not show that a control was carried out.

Agree the relevant record period rather than applying one three- or six-month rule to every business. Consider the assessment request, applicable retention requirements, changes in operations and the evidence needed to explain an issue. Where the request is unclear, confirm it with the assessor.

• Current scope and instructions: registration or system information, current procedures and documents for activities that have changed.
• Relevant completed checks: examples for the controls used in your operation, such as receiving, cleaning, allergen or temperature controls where applicable.
• Exceptions and responses: records showing what happened when a check was outside the expected result and what action followed.
• Previous findings: the actual report, assigned actions, supporting evidence and any response from the formal assessor.
• Supporting information: appropriate supplier, maintenance, calibration, training or product information where it is relevant to the assessed work.

This is a selection guide, not a statement that every listed document or monitoring frequency applies to every business. Choose examples that help explain normal operation and relevant exceptions. Do not present only the neatest records while leaving known gaps unexplained.

Walk through procedures alongside actual practice

A practical readiness review follows a relevant activity through the operation. Put the current instruction beside completed examples and ask the person responsible to explain and demonstrate the task. Check whether the equipment, process and responsibilities match what the documents describe.

For example, a cleaning review could compare the instruction for a particular item of equipment, a completed record and the way the task is performed. If the equipment or method has changed, identify which instructions, checks and staff guidance need review. This is an illustrative preparation check, not a prescribed audit method.

Include changes, handovers and exceptions that affect the assessed scope. Note information that a document review cannot establish and whether observation onsite is needed. If a control’s adequacy requires specialist evidence, keep that question visible rather than treating tidy paperwork as its answer.

Prepare the team and arrange useful site access

Discuss the assessment with the people who perform and supervise the relevant work. Focus on understanding their actual responsibilities and locating the information they use. Practical questions can reveal where an instruction is unclear or where further guidance is needed.

• Can the person explain the task and show the current instruction or record?
• Do they know the checks and limits that apply to their own work?
• Can they explain what to do when something is wrong, including who to tell?
• Is someone available who can answer questions about scope, process changes and unresolved actions?

Use genuine explanations rather than rehearsed answers. Where the team needs help, arrange relevant food safety training and practical staff guidance. Confirm access, visitor arrangements, relevant production times and access to electronic records with the assessor. Do not assume a visit during an inactive period can show how an operating control works.

Turn readiness gaps into assigned actions

Keep a short action list that connects each issue to the relevant requirement or question. Identify the next step, the person responsible, the target date and the evidence needed to demonstrate completion. Separate a confirmed gap from a point that still needs clarification.

Prioritise work according to the issue and its significance, not the order in which it appears in a folder. A concern affecting food safety needs appropriate action when identified; an approaching audit is not a reason to leave it until the visit. Escalate uncertain technical decisions to the appropriate competent person.

For previous findings, distinguish work the business has completed from formal acceptance of the response. Have the report, actions and evidence available, and identify anything still outstanding. Our guide to responding after a failed food safety audit or verification deals with the separate post-assessment response and close-out process.

Brief AFVA on a focused pre-audit readiness review

Access Food Verification & Auditing Limited provides food safety audit preparation support. Its current service includes document and record review, gap assessment, a practical action plan, staff and site readiness guidance, evidence preparation and follow-up within the agreed engagement.

A useful first enquiry sets out the assessment type and criteria, date, location, current scope and the question you need help to resolve. Provide the current plan or system, previous report and relevant completed record examples. Identify missing information honestly, and say who can answer operational questions.

Agree the work and output before commissioning it. For example, a focused review might produce a prioritised gap list and practical next steps for your team. Clarify whether the work includes a site visit, document changes, staff guidance or follow-up, and which actions remain with the business or another specialist.

If you want a separately commissioned internal audit with its own criteria, sampling and report, use the internal food safety audit briefing guide to define that different assignment. Readiness support should not be described as a completed formal verification or certification assessment.

Some preparation can suit remote document review and discussions; practical observation may need an onsite visit. AFVA can discuss the appropriate arrangement and availability. Advice about preparation does not guarantee an audit result or establish that the same provider can undertake a separate formal assessment.

Preparation mistakes to avoid

• Starting with a generic record list. Confirm the actual criteria and scope before deciding what evidence is relevant.
• Checking documents without checking practice. Compare instructions with real tasks and completed records.
• Leaving actions without owners. Assign responsibility and identify evidence still needed.
• Confusing planned work with completion. A promised change, an implemented change and acceptance of evidence are different stages.
• Assuming preparation secures a pass. The formal assessor considers the actual operation and applicable requirements.

Frequently asked questions about audit preparation

Prepare a clear next step for your business

Write down the assessment, scope, deadline and the issue you need help with. Bring the current information and genuine examples of how the business operates. A focused review can then address the work that matters to your team.

General information only: Requirements depend on the complete food activities, products, processes, locations and sales model, and the applicable assessment criteria. Use current official guidance and confirm the requirements applying to your business before relying on a classification, timeframe or record list.
