The correct regional anniversary calendar comes from the rule, agreement or policy governing the calculation. It does not necessarily come from your present location.
The source may point to the province where an employee usually works, the province where a property is situated or the region where a court is situated. Some statutory definitions do not exclude a regional anniversary at all. Check that source before selecting Region in the calculator.
Different sources use different locations
For employment, Employment New Zealand says an employee can claim only one regional anniversary day each year. If an employee usually works in one province but is temporarily working in another, the employer and employee should agree which anniversary to observe. If they cannot agree, the employee observes the anniversary of the province where they usually work.
The standard TLANZ/REINZ Agreement for Sale and Purchase uses a different test. Its published sample excludes the anniversary day of the province in which the property is situated. Another contract may use different wording, so the signed agreement remains the source for a private calculation. The property-settlement guide shows how the property location affects a ten-working-day period.
Court rules can use the court's location. High Court Rules 2016 r 3.2, for example, lists the anniversary day of the region in which the court is situated as a court holiday. The parties' locations do not change that wording. Check the applicable court rule as well as any operational notice about a particular registry.
The Resource Management Act 1991 takes another approach. Its working-day definition excludes named national holidays and the period from 20 December to 10 January, but it does not exclude a regional anniversary. For a statutory RMA count, select the RMA (20/12 ↔ 10/1) shutdown and No Anniversary. Add a region only if a separate rule requires it or you are deliberately comparing a local planning assumption. The RMA guide explains that definition and the summer exclusion.
The calculator has thirteen Region options
New Zealand's anniversary days relate to the former provinces. Those areas do not always match present-day council boundaries. The observed dates also depend on local custom, and several do not follow the usual nearest-Monday pattern.
| Calculator option | Usual pattern | Worth checking |
|---|---|---|
| No Anniversary | National public holidays only | Use this when the definition does not exclude an anniversary, or when you need a national baseline. |
| Auckland | Generally the Monday nearest 29 January | The former province includes places outside the present Auckland region, so confirm the area. |
| Canterbury | Christchurch Show Day, in northern and central Canterbury | Not for South Canterbury, which runs on a different date. |
| Chatham Islands | Generally the Monday nearest 30 November | Check the published date for the year you're counting. |
| Hawke's Bay | Friday before Labour Day | A local convention, not mondayisation. |
| Marlborough | First Monday after Labour Day | Confirm the current local date. |
| Nelson | Generally the Monday nearest 1 February | The observed area includes Tasman and Buller; check both the location and date. |
| Otago | No single clearly settled day | For employment, use the agreement or custom and practice; if neither supplies an answer, the parties should agree a date. |
| South Canterbury | Fourth Monday in September, tied to Dominion Day | Select it separately from Canterbury. |
| Southland | Normally Easter Tuesday | Not simply the Monday nearest a historical date. |
| Taranaki | Second Monday in March | The convention keeps it clear of Easter. |
| Wellington | Generally the Monday nearest 22 January | The observed area includes Manawatu and Whanganui; confirm the location and date. |
| Westland | Varies within Westland | Employment New Zealand notes Greymouth observes the official day; elsewhere needs a local check. |
Employment New Zealand says anniversary days are generally observed on the Monday nearest the historical date, subject to these local exceptions. Its annual table also warns that it may contain errors. Confirm the relevant year's date with the regional or city council before relying on a deadline.
Auckland changes this result by one working day
Start on Friday 23 January 2026 and count one working day forward, excluding the start date. The result depends on the Region selection:
| Region setting | Result | Why |
|---|---|---|
| No Anniversary | Monday 26 January 2026 | Saturday and Sunday are excluded |
| Auckland | Tuesday 27 January 2026 | Monday 26 January is Auckland Anniversary Day and is also excluded |
Both examples use the same setup. Only the Region changes:
- Mode: Default Mode → Deadline
- Start date: 23 January 2026
- Direction: Forward
- Period: 1 working day
- Include start date: off
- Include deadline date: on
- Shutdown Period: No Shutdown
Open the Auckland calculation. The result should name Auckland as the selected calendar and list Auckland Anniversary Day among the excluded dates.
Several regions create a combined planning calendar
The Region control accepts more than one named region. The calculator then excludes a date if it is an anniversary day in any selected region. This can help find dates when, for example, Auckland and Wellington offices are both open.
This combined calendar does not give an employee two anniversary entitlements or establish that a deadline rule uses both regions. It is appropriate only when the source requires several calendars or when you are intentionally building a wider planning calendar.
No Anniversary cannot be combined with a named region. Selecting No Anniversary clears all named regions. Selecting a named region clears No Anniversary, after which you can add further named regions.
Check the selected calendar and the observed date
Once the calculation runs, check the region named in the result and each anniversary shown in the non-working-day breakdown. Those details confirm what the calculator applied. They do not establish which province a property belongs to, which anniversary an employment arrangement observes or which definition governs a legal period. Those inputs still come from the relevant source.
