Casual Employment – A Quick Guide for N.Z Employers
Casual employment can give your business flexibility, letting you offer work ‘as and when required.’ However, New Zealand employment law looks beyond labels – it focuses on the actual nature of the working arrangement, and many employers have faced legal problems from not understanding casual employment.
Incorrectly managing casual employment relationships can expose employers to legal claims, including successful personal grievances for unjustified dismissal or disadvantage and arrears claims for things like failing to manage holiday and leave entitlements correctly.
What is Casual Employment?
There is no statutory definition of casual employment in New Zealand. In practice, casual employment exists where:
Work is offered and accepted on an as-needed basis.
There is no clearly defined pattern, or regularity of work performed by a casual employee.
There is no expectation of ongoing work.
Neither party has obligations between periods of work, and the employee can decline offers of causal work without issue.
The Employment Relations Authority (‘the Authority’)and Employment Court (‘the Court’) look at how the relationship operates, not just what the employment agreement states. This means how an employee who is employed under a casual employment agreement works in practice is of vital importance.
Working practices should be closely monitored by employers to ensure casual arrangements do not evolve into permanent employment relationships overtime, which is a frequent problem that employers encounter when using casual employees.
Why Classification Matters?
Misclassifying employees as casual when the true relationship is ongoing or permanent can expose employers to claims for:
Unjustified dismissal if work stops without a fair process.
Back pay for statutory entitlements (e.g. annual leave, sick leave, public holidays, etc).
Unjustified disadvantage claims and compliance penalties for failure to manage legal obligations correctly.
These risks can materialise in situations where employers incorrectly manage casual employment agreements such as in situations where casual employees work regular days and hours each week and therefore should be employed on a permanent part-time or full-time basis – not casual basis.

Case Law Snapshot – What Recent Decisions Tell Employers
Stevenson v Mountain Chalets (2005) Limited [2025] NZERA 248
A cleaner was engaged under a ‘casual’ agreement but worked 20 – 25 hours weekly over several years. When the employee’s hours were significantly reduced an employment dispute arose. The employer argued the employee was casual and therefore could not claim unjustified dismissal.
The Authority examined whether the work pattern was truly casual or whether it had become a de facto permanent arrangement. The Authority found in favour of the employee and awarded her compensation of $8,000 for her unjustified disadvantage claim and outstanding holiday related entitlements, including holiday pay for the entire duration of her employment since she was not a causal employee (excluding the employer’s own legal costs). She was found to be a permanent part-time employee.
Employer Takeaway: Regular and predictable hours of work can transform a nominally casual arrangement into a permanent employment relationship, with all associated rights, obligations and entitlements. Casual employment agreements must not be used where an employee works regular days and the same hours each week.
Hoebergen v Amline Freighters Limited [2023] NZERA 193
A truck driver engaged as a ‘casual’ employee worked regular and predictable hours over an extended period. When work was stopped during a downturn, the employer relied on the casual label.
The Authority found the relationship had become permanent in nature, requiring a fair process before ending employment. Simply ceasing work offers amounted to an unjustified dismissal, and the employer was ordered to pay $8,000 in financial remedies (excluding the employer’s own legal costs).
Employer Takeaway: A ‘casual’ label does not guarantee casual status. Regular and predictable work can change the relationship to permanent, triggering obligations such as fair process before ending employment.
Practical Steps for Employers
Set clear expectations in writing. Make sure employment agreements accurately reflect how work will be offered and what it means to be casual.
Monitor work patterns. Regular, predictable hours or rostering may indicate a permanent relationship, even if the contract says casual.
Communicate about entitlements. Ensure casual employees understand their rights including that they can decline casual offers of work and employment entitlements.
Common Employer Pitfalls
Assuming the contract label is decisive – the courts look at actual working arrangements.
Offering regular work month after month without reviewing employment status.
Ending a casual employee’s engagement mid-period without following a fair process.
Compliance Warning
Casual employment is valuable for flexibility but must reflect genuine casual work in practices, not just in name. Employers must be careful to match casual employment agreements with reality, monitor work patterns, and comply with legal obligations.
Failure to correctly manage causal employment agreements can result in successful personal grievance claims and financial orders against an employer, including back pay for failing to manage holiday related entitlements correctly. Employers should review their employment agreements and practices to ensure compliance and seek professional advice if there is uncertainty.
