How many business days are there in a year in NZ?

New Zealand has approximately 250 to 252 business days per year, depending on which days the public holidays fall on. In 2026, there are 11 national public holidays (plus your regional anniversary day), and weekends account for 104 days, leaving approximately 250 working days. The exact number varies slightly each year because some holidays can fall on weekends and may or may not be Mondayised.

What are business days in NZ?

Business days (also called working days) in New Zealand are Monday to Friday, excluding public holidays. Saturday and Sunday are not business days. The 11 national public holidays and your regional provincial anniversary day are also excluded. Business days are used for calculating legal deadlines, settlement dates, payroll periods, and contractual timeframes.

Does this calculator include Matariki?

Yes. Matariki has been a public holiday since 2022. The date changes each year as it is set by the Matariki Advisory Committee based on the Maori lunar calendar. For 2026, Matariki falls on Friday 10 July. For 2027, it falls on Friday 25 June. The calculator includes Matariki for all years from 2022 onwards.

How does Mondayisation work for business day calculations?

Mondayisation applies to Waitangi Day and Anzac Day only. If either falls on a Saturday or Sunday, the following Monday is observed as the public holiday instead. For business day calculations, the Monday is excluded (not the Saturday/Sunday). Christmas Day, Boxing Day, New Year's Day, and the Day after New Year's Day have separate transfer rules when they fall on weekends.

What is 10 business days from today in NZ?

Use this calculator to find the exact date. Enter today's date as the start, select 'Add business days' mode, and enter 10. The calculator will skip weekends and any NZ public holidays that fall within the period, giving you the correct target date. This is commonly used for Tenancy Tribunal response deadlines (10 working days), ACC claim timeframes, and contractual notice periods.

How Business Days Are Counted

A business day is any day that is not a Saturday, Sunday, or public holiday. When legislation or contracts refer to "working days," they typically mean business days. The start date is usually not counted (the count begins from the next day), but this can be configured in the calculator.

Common Uses

Tenancy Tribunal response deadlines (10 or 14 working days)
Property settlement dates
Employment notice periods
Resource consent processing timeframes
ACC claim and review deadlines
IRD correspondence response periods
Bond lodgement (23 working days)
