How To Reduce Staff Hours Without Legal Risk

In New Zealand, you generally can't just reduce an employee's hours if those hours are guaranteed in their employment agreement. You usually need the employee's agreement, a clear contractual right, or a fair restructure process where the role genuinely needs to change.

If your business is under pressure, reducing hours can still be possible. The key is to slow down, check the contract, consult in good faith, and document the outcome properly so you don't create a bigger employment problem than the cost issue you're trying to solve.

Can My Employer Reduce My Hours NZ?

For employers, the practical answer is: it depends on what the employment agreement says and how the change is handled.

If the agreement says the employee works 40 hours per week, or has a minimum of 30 hours per week, those hours are usually a core term of employment. Cutting below that number without agreement can amount to a breach of the employment agreement. It can also expose your business to unpaid wage claims, penalties, and a personal grievance if the employee says the process was unjustified.

If the agreement says hours are rostered or variable, you may have more room to move. But roster flexibility isn't a blank cheque. You still need to act fairly, in good faith, and consistently with the Employment Relations Act 2000. If an employee has worked the same pattern for a long time, that pattern may also matter in practice, even if the written contract isn't perfectly clear.

As a starting point, review the Employment Contract, any written variations, current rosters, payroll records, job descriptions, and any messages that confirm agreed hours. You want to know what the employee is legally entitled to before you decide what options are available.

Can You Cut Employee Hours Or Full-Time Hours?

You can reduce full-time hours if the employee agrees to the change, or if you follow a proper process because the full-time role is genuinely no longer required in its current form. What you shouldn't do is simply publish a new roster that cuts a full-time employee from 40 hours to 25 hours and treat that as the end of the matter.

There are three common scenarios.

• Guaranteed full-time hours: a reduction should be recorded in a written variation to the employment agreement, agreed in writing and signed by both the employer and employee before the change starts.
• Rostered hours with a minimum: you can change the roster within the agreed framework, but shouldn't go below the guaranteed minimum unless the employee agrees or a fair restructure process supports the change.
• Genuinely casual work: you may be able to offer fewer shifts, but be careful if the person has been working regular, ongoing hours and looks more like a permanent employee in practice.

New Zealand employment law also has specific rules around availability and shift cancellation. If you require an employee to be available for work, the agreement should include a genuine availability provision, guaranteed hours, and reasonable compensation for availability where required. If you cancel shifts, the agreement should deal with notice and compensation. These clauses matter because reducing hours often happens through rosters, not just through formal letters.

If your workplace uses casual staff, check whether the arrangements still match reality. A person called casual on paper may have stronger rights if they work predictable hours over a long period. It's also worth checking how leave and entitlements are being handled, especially if your staffing model has changed. You can read more about casual workers leave entitlements.

Temporary Reduction In Hours Vs Permanent Change

A temporary reduction in hours is often easier to discuss with staff because it gives everyone a defined review point. But it still needs to be clear, voluntary where agreement is required, and properly recorded.

A temporary arrangement might say, for example, that an employee's hours will reduce from 40 to 32 hours per week for eight weeks, starting on a particular date, with a review in week six. It should also say what happens at the end of the period. Do hours automatically return to normal? Will the parties meet again? Could the business propose a further change if trading hasn't improved?

A permanent reduction is more serious. Moving someone from full-time to part-time can affect income, leave calculations, role expectations, career progression, and whether the original role still exists. If the role is fundamentally changing, you may be in restructure territory rather than a simple hours variation.

Be especially careful with pay. If you reduce hours and salary together, the employee's pay must still comply with minimum employment standards, including the current minimum wage for all hours worked. Minimum wage rates can change, so confirm the current rate on the MBIE website or with your payroll adviser before implementing a new pay arrangement.

Reduced hours can also affect annual holiday pay, ordinary weekly pay, average weekly earnings, sick leave payments, public holiday entitlements, KiwiSaver deductions, and payroll reporting. The Holidays Act 2003 can be technical, particularly where work patterns become variable. If the payroll impact is material, check the calculations before you confirm the change.

How To Reduce Staff Hours Lawfully

The safest path is usually a fair consultation process followed by a written agreement or, where required, a restructure outcome. Even if your business reasons are genuine, the process matters.

1. Check The Contract And The Actual Working Pattern

Look at the employment agreement first, then compare it with what is happening in real life. Ask:

• Are there guaranteed minimum hours?
• Are days and times fixed?
• Is there a rostering clause, availability provision, or shift cancellation clause?
• Have the employee's hours changed informally over time?
• Are there any collective agreement terms, policies, or past written variations?

2. Prepare A Real Business Reason

Cost pressure can be a valid reason, but you need more than a vague statement that things are quiet. Prepare enough information to explain the problem. This might include reduced bookings, lower revenue, lost clients, increased supplier costs, reduced opening hours, or seasonal demand changes.

3. Put A Proposal To The Employee

Give the employee a written proposal before making a final decision. The proposal should explain what you're considering, why, when it could start, whether it's temporary or permanent, and what alternatives you have thought about. Make it clear that no final decision has been made.

4. Consult In Good Faith

Good faith means you give relevant information, allow a genuine opportunity for feedback, and keep an open mind. The employee might suggest job-sharing, different shift times, using annual holidays by agreement, reducing overtime, redeploying duties, or a shorter temporary reduction. You don't have to accept every idea, but you do need to consider them properly.

5. Confirm The Outcome In Writing

If the employee agrees, record the new arrangement in a written variation. If they don't agree and the business still needs to remove or reduce the role, take advice before moving to a restructure decision. Forcing the change through can create avoidable risk.

What Should A Written Hours Reduction Proposal Include?

A written proposal helps show that you have approached the change carefully and in good faith. It also gives the employee something clear to respond to, rather than relying on a stressful conversation about reduced income.

A practical outline might include:

1. Opening And Purpose: explain that the business is proposing a change to hours and that no final decision has been made.
2. Business Reasons: summarise the financial, operational, seasonal, or client-related reasons for the proposed reduction.
3. Current Arrangement: record the employee's current role, hours, pay basis, and relevant contract terms.
4. Proposed Change: set out the proposed new hours, days, start date, pay impact, and whether the change is temporary or permanent.
5. Alternatives Considered: note options such as reduced opening hours, voluntary reductions, job-sharing, leave by agreement, or other cost controls.
6. Consultation Process: invite feedback, give a reasonable deadline, and offer a meeting where the employee can bring a support person if they wish.
7. Next Steps: explain when you'll consider feedback and when you expect to confirm the outcome.

A lawyer or employment adviser should tailor the proposal to the specific contract, workplace, and reason for change. A template can be useful, but it shouldn't be used in a way that makes the decision look predetermined.

Worked Example: Reducing Hours In A Small Cafe

Imagine you run a cafe in Wellington with four employees. One full-time employee, Mia, is contracted to work 40 hours per week at $28 per hour. Your weekday afternoon trade has dropped, and your weekly wage cost for Mia is $1,120 before deductions. You think the business can only support 32 hours per week for the next three months, which would reduce that wage cost to $896 per week. The saving is $224 per week, or $2,912 over 13 weeks.

Even though the numbers make commercial sense, you can't simply roster Mia for 32 hours if her agreement guarantees 40. A better process would look like this:

• You check Mia's employment agreement and confirm it guarantees 40 hours per week.
• You prepare sales data showing the afternoon downturn and why the cafe is considering shorter afternoon opening hours.
• You give Mia a written proposal to reduce hours from 40 to 32 for 13 weeks, with a review after 10 weeks.
• You meet with Mia, invite feedback, and consider her suggestion that she work 36 hours instead, with one afternoon shift moved to a busier Saturday.
• You review the numbers and decide that 36 hours plus the Saturday shift still achieves enough savings and better matches customer demand.
• You confirm the agreed temporary variation in writing, including the start date, review date, new roster, pay impact, and that the original 40-hour arrangement resumes unless another agreement is reached.

The outcome isn't just legally safer. It's also more likely to preserve trust because Mia can see the business reason, had a real say, and knows when the arrangement will be reviewed.

Common Risks When Reducing Employees' Hours

Reducing hours can go wrong quickly if the change is rushed or treated as a simple rostering decision. Watch out for these common traps.

Unilateral Roster Cuts

If an employee has guaranteed hours, cutting the roster below those hours can create arrears and personal grievance risk. Don't assume a rostered workplace means all hours are optional.

Predetermined Consultation

Consultation isn't just announcing a decision. Avoid saying things like, everyone has to accept this, sign today, or there's no alternative. If the outcome is already locked in, the process may be criticised even if the business reason is genuine.

Using Annual Leave As A Quick Fix

Annual holidays can sometimes help manage quiet periods, especially by agreement. If you can't agree on when annual holidays are taken, the Holidays Act generally requires at least 14 days' notice before directing annual holidays. Closedown rules have their own requirements. Before using leave as a cost-control tool, check the rules around annual leave.

Accidentally Creating A Redundancy

If your proposal means a full-time role no longer exists and only a part-time role remains, that may be a restructure. You may need to consult on the proposed change, consider alternatives, and deal fairly with affected employees. New Zealand redundancy compensation isn't automatic under statute for every employee, but it may be required by the employment agreement or workplace policy. This overview on redundancy is a useful starting point.

Replacing Employees With Contractors

Some businesses respond to fluctuating demand by using contractors. That can be legitimate, but only where the arrangement is genuinely contracting. From 2026, New Zealand's Employment Relations Act changes include a contractor gateway test that can help determine when a worker won't be treated as an employee. Broadly, it looks at factors such as having a written contractor agreement and whether the worker has real independence, including the ability to work for others and decline work. Check current MBIE guidance before relying on the gateway, because the wording and practical application matter.

If someone works like an employee, calling them a contractor won't always solve the problem. Where you do need contractors, having the right contractor arrangement and supporting documents makes a big difference.

Step-By-Step Checklist Before You Reduce Hours

Before changing staff hours, work through this checklist.

1. Identify the business reason: write down the financial or operational reason and gather supporting information.
2. Check the contract: confirm whether hours are guaranteed, rostered, variable, or casual, and look for availability or cancellation clauses.
3. Check minimum standards: make sure the proposed arrangement still complies with minimum wage, Holidays Act, record-keeping, and payroll obligations.
4. Decide whether this is a variation or restructure: if the role is fundamentally changing, use a restructure-style consultation process.
5. Prepare a written proposal: explain the proposed change, the reasons, the timeframe, and the feedback process.
6. Consult properly: meet, listen, consider alternatives, and avoid presenting the outcome as already decided.
7. Document the outcome: use a written variation, updated roster, revised job description, or restructure outcome letter as appropriate.
8. Update systems: align payroll, leave calculations, policies, and manager instructions with the agreed arrangement.

If the same issue keeps coming up, it may be worth reviewing your employment documents more broadly. Your contracts, rostering practices, casual arrangements, and policies should match how your business actually operates.

Key Takeaways

• You usually can't reduce guaranteed staff hours without agreement or a fair process that supports the change.
• The employment agreement is your starting point, especially any guaranteed hours, rostering, availability, or shift cancellation clauses.
• Temporary reductions still need clear written terms, including start dates, review dates, pay impact, and what happens when the period ends.
• Consultation must be genuine: share the business reason, invite feedback, consider alternatives, and avoid predetermined decisions.
• A major hours reduction may be a restructure, particularly where a full-time role is being replaced with a part-time role.
• Check payroll, leave, and contractor risks before implementing changes, as these are common areas where small businesses get caught.
