Complaints happen in every business. It might be a customer unhappy with a refund, a client frustrated about service quality, or an employee raising a serious concern about behaviour at work.
The difference between a “small issue” and a costly dispute often comes down to one thing: whether you have a clear complaint policy, and whether your team actually follows it.
This guide is updated for current expectations and best practice. While the core legal principles haven’t suddenly changed, regulators and customers are increasingly focused on fast, fair processes, privacy-safe record keeping, and consistent decision-making (especially when complaints come in through online channels).
Below, we’ll walk you through how to build and implement a complaint policy that’s practical, legally mindful, and easy for your staff and customers to use.
What Is A Complaint Policy And Why Does It Matter?
A complaint policy is a written process that explains:
- how someone can make a complaint (and who they complain to),
- how you’ll investigate and respond,
- what timeframes apply, and
- how you’ll record, store, and learn from complaints.
In plain terms: it’s your game plan for handling problems consistently.
Without a complaint policy, you’re relying on individual judgement under pressure. That’s when businesses accidentally:
- make inconsistent decisions (which can look unfair or discriminatory),
- say the wrong thing in writing (and create evidence that can be used against them later),
- breach privacy by oversharing information, or
- escalate a situation by responding emotionally or defensively.
Who Is The Complaint Policy For?
Most NZ businesses benefit from thinking about complaints in two streams:
- Customer complaints (about goods, services, billing, refunds, advertising, delays, quality issues, and misunderstandings).
- Workplace complaints (about performance issues, interpersonal conflict, bullying, harassment, discrimination, safety concerns, or breaches of company policy).
You can handle both with one overarching policy, or have separate policies depending on your business size and risk profile. Either way, the key is that the process is clear and actually workable.
Why A Complaint Policy Helps Your Business (Beyond Compliance)
An effective complaint policy can help you:
- resolve issues earlier (before lawyers, tribunals, or online reviews get involved),
- protect your team by providing a fair, structured process,
- protect your brand by keeping communications professional and consistent,
- spot patterns (like recurring product faults, training gaps, or customer experience issues), and
- reduce legal risk because you can show you followed a reasonable process.
What Laws Should Your Complaint Policy Consider In New Zealand?
A complaint policy isn’t “one law, one policy”. It’s a practical document that sits across several NZ legal obligations.
Here are the key areas to keep in mind (and why they matter).
Consumer Law (If Customers Are Complaining)
If you sell goods or services to consumers, your complaints process should align with consumer protection rules, including:
- Fair Trading Act 1986 (for misleading conduct, representations, pricing claims, and advertising), and
- Consumer Guarantees Act 1993 (for guarantees around acceptable quality, fitness for purpose, and remedies).
Many complaints come down to expectations around refunds, repairs, replacements, and how quickly issues are put right. Your policy should link with your customer-facing terms and your refunds approach, including any published returns refunds and exchanges position.
One important point: your policy can’t “contract out” of consumer law for typical consumer sales. A complaint policy is not the place to overpromise (“we refund everything, always”) or unlawfully restrict rights (“no refunds ever”).
Employment Law (If Staff Are Complaining)
If the complaint relates to an employee, your policy should support fair process and align with your wider employment documents, such as your Workplace Policy and your Employment Contract.
Workplace complaints often touch on:
- personal grievances (e.g. unjustified disadvantage, unjustified dismissal),
- bullying/harassment processes,
- disciplinary pathways, and
- confidentiality expectations during investigations.
Even if your complaint policy is “informal” in tone, the way you apply it needs to be procedurally fair. A messy process (or a process you don’t follow) is where risk builds.
Health And Safety (When A Complaint Is Really A Safety Issue)
Sometimes a “complaint” is actually a health and safety report in disguise. For example:
- “The storeroom is unsafe and nothing is being done.”
- “A customer slipped and staff didn’t know what to do.”
- “I’m being rostered in a way that’s causing fatigue.”
Under the Health and Safety at Work Act 2015, businesses must take reasonably practicable steps to provide a safe workplace. Your policy should explain how safety-related complaints are escalated quickly and recorded appropriately.
Complaints nearly always involve “personal information” (names, contact details, staff allegations, CCTV, order histories, emails, or call logs). That means your process needs to respect the Privacy Act 2020 and your own Privacy Policy.
In practice, this usually means:
- only collecting information you actually need to handle the complaint,
- sharing information only with people who genuinely need to know,
- storing complaint records securely (and limiting access), and
- having a plan for how long you keep records and how you dispose of them.
If you want a dedicated internal process for privacy-related complaints (for example, “you’ve mishandled my personal information”), a Privacy Complaint Handling Procedure can be a smart companion document.
What Should An Effective Complaint Policy Include?
A good complaint policy is clear, structured, and easy to follow on a busy day.
Below is a practical checklist of what we usually recommend including.
1. A Clear Definition Of “Complaint”
Define what you treat as a complaint so staff don’t ignore something important.
For example, you might define a complaint as:
- any expression of dissatisfaction about your goods, services, staff, or operations,
- that requires a response or resolution,
- whether it is made formally or informally (in person, email, phone, social media, or through a platform like Google reviews).
This is especially helpful for online businesses where “complaints” may arrive through DMs, comment sections, or third-party marketplaces.
2. How To Make A Complaint (And Alternative Channels)
Spell out the intake options clearly. For example:
- email address for complaints,
- online form (if you have one),
- in-store process (who the customer should ask for),
- phone line, and
- an alternative contact person if the complaint is about a manager/owner.
For workplace complaints, include an option that lets employees bypass their direct manager if that manager is involved in the complaint.
3. Timeframes (So You Don’t “Accidentally Ghost” Someone)
Timeframes reduce frustration and reduce follow-up emails. They also keep your team accountable.
A common approach is:
- Acknowledgement: within 1–2 business days.
- Initial assessment: within 3–5 business days (triage the issue and confirm next steps).
- Outcome target: e.g. within 10 business days, or if longer, provide updates every 7 days.
Be careful not to promise timelines your business can’t meet. It’s better to set realistic timeframes and then beat them.
4. Investigation Steps (In Plain English)
Your policy should explain what an investigation may involve, such as:
- reviewing order records, photos, service notes, or job sheets,
- speaking to staff members involved,
- reviewing CCTV or access logs (if relevant and lawful),
- asking the complainant for more information, and
- documenting findings and reasons for decisions.
This keeps the process fair, and it also signals to the complainant that you take the issue seriously.
5. Outcomes And Remedies (Including What You Can And Can’t Offer)
List examples of possible outcomes. For customer complaints, this might include:
- refund, replacement, repair, or credit (where appropriate),
- re-doing a service,
- an apology and explanation,
- training/coaching for staff, or
- declining the complaint with clear reasons (where the complaint isn’t upheld).
For workplace complaints, outcomes might include:
- informal resolution and agreed behaviour expectations,
- mediation,
- a formal warning process (where appropriate),
- changes to reporting lines or work arrangements, or
- disciplinary action (in serious cases).
It’s also helpful to clarify what you generally won’t do (for example, staff “punishment” without investigation, or providing compensation unrelated to the actual issue), while still allowing flexibility depending on the circumstances.
6. Escalation And External Options
Your policy should explain what happens if the complainant is unhappy with your response. For example:
- a review by a senior person not involved in the original decision,
- an option to request reconsideration if new information becomes available, and
- where relevant, external bodies (such as the Disputes Tribunal for smaller civil disputes, or an industry scheme).
You don’t need to include a long list of every external forum. The goal is to show you have a fair internal process and a genuine escalation pathway.
7. Confidentiality And Privacy Controls
Be upfront: you will treat complaints confidentially to the extent you reasonably can, but you may need to share information with people involved in investigating or resolving the issue.
This is where many businesses get caught out. If someone makes a complaint and the business starts forwarding emails around casually, you can end up with a privacy issue layered on top of the original complaint.
For staff-related matters, it can also help to align this section with an Employee Privacy Handbook approach, so employees understand what information is collected, why, and how it’s handled.
8. Record Keeping (And Why It’s Worth Doing)
Record keeping is what turns “we handled it fairly” into something you can actually demonstrate later.
Your policy should state:
- what you record (complaint details, evidence, steps taken, outcome, reasons),
- where it’s stored (system/location),
- who can access it, and
- how long you keep it.
Good records also help you improve your systems. If you notice the same complaint happening repeatedly, you can fix the root cause rather than dealing with the symptom every month.
How Do You Implement A Complaint Policy In Practice?
Writing a complaint policy is the easy part. Making it work day-to-day is where most businesses struggle.
Here’s a practical, step-by-step approach.
Step 1: Map Your “Real World” Complaint Touchpoints
Before you finalise the policy, list where complaints actually come in. For example:
- front counter conversations,
- customer support inbox,
- social media DMs,
- online marketplace messages,
- review platforms, and
- internal chats (Slack/Teams) or direct messages to managers.
If your policy only talks about emailing a generic address, but your customers mostly complain via Instagram, you’ll have a gap from day one.
Step 2: Assign Roles (So It Doesn’t Sit In Limbo)
Your policy should nominate:
- who receives complaints (and what to do if they’re away),
- who investigates (and how conflicts are managed), and
- who approves outcomes (especially if refunds/credits are involved).
If you’re a small business, this might be one person wearing multiple hats. That’s fine, as long as it’s clear.
Step 3: Train Your Team On The “How”, Not Just The “What”
Training doesn’t need to be complicated, but it should be specific.
For example, teach staff:
- how to acknowledge a complaint without admitting liability too early,
- how to stay polite and calm (even if the complainant isn’t),
- when to escalate immediately (e.g. threats, safety issues, discrimination allegations),
- what to put in writing (and what not to), and
- how to document interactions properly.
Tip: consider giving staff a short script for the first response, so they don’t freeze or accidentally inflame the situation.
Step 4: Make The Policy Easy To Find And Easy To Use
Implementation fails when the policy is buried in a shared drive no one opens.
Make sure:
- staff know where to access it,
- it’s included in onboarding, and
- there’s a short “quick guide” version for frontline staff.
For customer complaints, it’s often worth adding a short complaints section on your website or in your terms, so customers know how to raise issues without going straight to a public review.
Step 5: Build It Into Your Other Documents And Workflows
A complaint policy works best when it matches the rest of your business systems, including:
- your customer terms and service processes (especially around refunds and service standards),
- your internal HR processes, and
- your broader Workplace Policy framework.
In practice, this can be as simple as ensuring your staff know when a complaint becomes a “formal” matter, and what documents or checklists they must use next.
Step 6: Review Complaints Regularly (And Use Them To Improve)
Complaints are data. If you track them properly, they can show you where the business is leaking time, money, and goodwill.
Consider a monthly or quarterly review of:
- number of complaints received,
- common complaint categories,
- resolution timeframes,
- refund/credit totals (if relevant), and
- process improvements (training, updated scripts, clearer product descriptions, better instructions).
Common Mistakes To Avoid
Most complaint policies fail for predictable reasons. Here are the big ones to watch for.
Having A Policy That’s Too Vague
“We take complaints seriously” is nice, but it’s not a process.
If your policy doesn’t set out timeframes, steps, or responsibilities, staff will fill in the gaps themselves (and you’ll get inconsistent outcomes).
Overpromising Outcomes
Be careful about absolute statements like:
- “We will always refund you if you’re unhappy.”
- “All complaints will be resolved in 48 hours.”
- “All investigations will be fully confidential.”
These can be hard to deliver on, and they may create expectations you can’t meet. It’s usually better to promise a fair process, a prompt response, and clear communication.
Not Managing Conflicts Of Interest
If the person investigating is also the subject of the complaint (or a close colleague/friend), the process can look biased even if the outcome is reasonable.
This is where it helps to build in an “alternative decision-maker” option, or align your process with a Conflict Of Interest Policy approach for internal matters.
Turning A Complaint Into A Public Argument
When a complaint appears on social media or in a review, it’s tempting to defend yourself publicly.
But public back-and-forth can:
- escalate the situation quickly,
- expose personal information, and
- create screenshots that live forever.
A better approach is usually to respond politely, invite the person to contact you directly, and follow your internal complaint handling process from there.
Failing To Document What Happened
Even if you resolve most complaints quickly, you should still record the essentials. Without records, you may struggle to respond if:
- the customer comes back months later,
- a staff complaint escalates, or
- you need to show you followed a fair process.
Key Takeaways
- An effective complaint policy gives you a consistent, fair way to handle issues before they escalate into disputes, reputational damage, or legal claims.
- Your complaint policy should be practical and easy to follow, with clear timeframes, responsibilities, investigation steps, and escalation pathways.
- Customer complaints often trigger consumer law obligations (including the Fair Trading Act 1986 and Consumer Guarantees Act 1993), so be careful not to overpromise or unlawfully restrict rights.
- Workplace complaints should align with fair employment processes and your wider documents (like a Workplace Policy and Employment Contract), especially where allegations are serious.
- Privacy should be built into every stage of complaint handling, including what information you collect, who you share it with, and how securely you store records.
- The best complaint policies are implemented through training, simple scripts, accessible workflows, and regular reviews of complaint trends (so you can fix root causes).
