Construction Leave Management in NZ: Weather Days and Close-Downs

New Zealand construction companies operate in an environment where leave management intersects with weather disruptions, annual close-down periods, project-based work, and the Building and Construction Industry Employment Agreement. The Holidays Act 2003 creates specific obligations around close-downs, alternative holidays for public holidays worked, and the OWP vs AWE pay rule that affect construction differently than office-based businesses.

A poorly managed annual close-down can leave you owing employees money they did expect — or paying them when you did not need to. Weather-related stand-downs create ambiguity about whether leave was taken or work was unavailable. And variable hours on project-based work make annual leave calculations genuinely complex.

This guide covers the Holidays Act challenges specific to NZ construction and how to manage them.

Key Takeaways

• Annual close-downs during the Christmas/New Year period are common in construction, but the Holidays Act has strict rules about how they affect annual leave entitlements.
• Weather days create ambiguity — are they unpaid stand-downs, annual leave, or something else? The answer depends on the employment agreement and the circumstances.
• Construction workers on variable project hours require careful OWP and AWE calculation, especially when projects finish and new ones begin.
• Leave management software tracks close-downs, weather days, and variable-hour leave calculations accurately.

Annual Close-Downs in Construction

Many construction companies close for 2–3 weeks over Christmas and New Year. This is standard industry practice, but the Holidays Act has specific rules about how it works:

If the close-down is in the employment agreement: The employer can require employees to take annual leave during the close-down period. The Holidays Act permits this as long as the close-down period is specified in the employment agreement or a collective agreement. The employer gives at least 14 days’ notice.

If the close-down is NOT in the employment agreement: You cannot force employees to take annual leave. The close-down is treated as a stand-down period. If the employee has accrued annual leave, you can direct them to take it. If they have no accrued leave, you may need to pay relevant daily pay for the days the workplace is closed — or the employee takes unpaid leave if that is consistent with the agreement.

The critical trap: During a close-down, employees continue to accrue annual leave. An employee on a 3-week close-down who has no accrued leave still accumulates approximately 0.75 weeks of annual leave during that period. If you then force them to take that accrued leave immediately upon return, you have effectively denied them the leave they earned — which the Holidays Act does not permit.

Many construction companies get this wrong because they do not understand the interaction between directed leave, close-down periods, and accrual. The result is employees who are owed money at the end of their employment because their leave balances were incorrectly maintained.

Weather Days: The Ambiguity Problem

Construction is weather-dependent. Rain, high winds, and extreme temperatures can prevent work on a given day. The treatment of weather days depends on the employment agreement:

Guaranteed hours with weather as employer risk: If the employment agreement guarantees a minimum number of hours per week and the weather prevents work, the employer may still owe the employee their guaranteed hours — effectively paying for a day no work was done. This is not annual leave; it is the employer bearing the weather risk.

No guaranteed hours: If the employee is paid only for hours actually worked and the weather prevents work, the day is unpaid. The employee is not on leave — they are simply not working. No annual leave deduction is required.

Mixed arrangements: Many construction employment agreements contain specific weather-day clauses. Some allow the employer to direct employees to take annual leave on weather days. Others treat weather days as stand-downs at the employer’s cost. The Building and Construction Industry General Collective Agreement contains provisions for weather-related stand-downs.

The compliance risk is treating a weather stand-down as annual leave when the employment agreement does not permit it. If you deduct annual leave for weather days and the agreement does not allow it, you are effectively forcing employees to take leave they did not agree to — which is a breach of the Holidays Act.

Public Holidays in Construction

Construction sites typically do not operate on public holidays, but the obligation still applies:

• If a public holiday falls on a day the employee would normally work and you are closed: The employee is entitled to relevant daily pay for the day.
• If a public holiday falls on a day the employee does not normally work: No payment is owed.
• If the employee works on a public holiday (common on projects with tight deadlines): Time-and-a-half plus an alternative holiday.

For construction, the key issue is that many employees work five-day weeks (Monday to Friday), so Saturday public holidays like Anzac Day 2026 (25 April, observed Monday 27 April) only affect employees who would otherwise work on the Monday. This is the Mondayisation rule — it shifts the entitlement to the Monday for employees who do not normally work Saturday.

Variable Hours and OWP/AWE

Construction workers often have variable hours — overtime on busy projects, short days when weather closes a site early, and gaps between projects. This makes OWP calculation challenging.

The Holidays Act requires you to pay the greater of OWP and AWE for annual leave. For a builder who earned $85,000 in gross earnings over the last 12 months (including regular overtime and site allowances), the AWE is $1,635/week. If their OWP based on the last 4 weeks is $1,400/week because of shorter days, the AWE figure governs. Paying only the $1,400 is an underpayment.

This is particularly important when projects finish and a new one begins. An employee who was earning high overtime on a large project and then starts a smaller project with fewer hours may have an AWE that significantly exceeds their current OWP. The annual leave calculation must use the AWE.

Construction Employment Agreements and Leave

The Building and Construction Industry Employment Agreement sets minimum terms for many construction workers. Key leave-related provisions include:

• Annual leave: 4 weeks per year, consistent with the Holidays Act
• Sick leave: 5 days per year (increased to 10 days under the Holidays Act in 2021, but some collective agreements may still reference the old entitlement — check your agreement)
• Bereavement leave: As per the Holidays Act
• Public holidays: As per the Holidays Act
• Weather stand-downs: Specific provisions that may differ from the Holidays Act default
• Annual close-down: Permitted with 14 days’ notice

You must comply with both the Holidays Act and your applicable employment agreement, whichever provides the greater benefit to the employee.

What Good Leave Management Looks Like for NZ Construction

A leave management system for construction should handle:

• Close-down tracking — directed annual leave during close-downs, with correct accrual calculations
• Weather day recording — distinguishing between weather stand-downs, annual leave, and unpaid days
• OWP and AWE automation — correct calculations for variable-hours workers
• Alternative holiday tracking — for public holidays worked on site
• Project-based visibility — who is available for the next project phase
• Multi-site support — tracking leave across different project sites
• Final pay accuracy — including any outstanding leave, close-down deductions, and weather-day adjustments

For construction businesses, the cost of getting leave wrong is not just financial — it is operational. Incorrect leave tracking creates disputes that distract from project delivery, and the ERA penalties for non-compliance can reach $20,000 per employee.

Getting Started

Start by reviewing your employment agreements — both individual and collective — for weather-day and close-down provisions. Then audit a sample of recent leave payments to verify you are applying the correct rules.

Then evaluate a leave management tool that handles NZ construction complexity. Leave Balance automates OWP and AWE calculations, tracks public holidays, and manages directed leave during close-downs.

Frequently Asked Questions

Can I force employees to take annual leave during a Christmas close-down?

Yes, if the close-down period is specified in the employment agreement or collective agreement and you give at least 14 days’ notice. If it is not in the agreement, you cannot force employees to take annual leave — you may need to pay them for the days the site is closed.

How do weather days affect annual leave accrual?

If the weather day is treated as a stand-down (not annual leave), the employee does not accrue annual leave for that day. If the weather day is treated as annual leave, they do accrue. The treatment depends on your employment agreement.

Does the 8% pay-as-you-go apply to casual construction workers?

Only for genuinely casual workers with no regular pattern and no expectation of ongoing employment. Many construction workers who are called “casual” actually work regular patterns and may be entitled to accrued annual leave under the Holidays Act.

What happens to annual leave balances when a project ends?

Nothing changes. Leave balances belong to the employee regardless of which project they are working on. When the employee moves to a new project or leaves the company, their accrued leave must be paid out if not taken.
