This chapter reflects general principles under the Canada–New Zealand Double Taxation Agreement as of May 2026. Tax law is complex. Consult a Canadian cross-border CPA and a registered NZ tax adviser before acting on any of this.

Two tests trigger NZ tax residency. The first: physical presence in New Zealand for more than 183 days in any 12-month period. The second: establishing a permanent place of abode in NZ - a settled, regular home- regardless of day count.

Both can apply simultaneously. A Canadian who signs a 12-month Auckland lease and starts work in week one is an NZ tax resident from day one under the permanent place of abode test.

From that point, IRD taxes worldwide income - Canadian salary, Canadian rental income, dividends from a TFSA, everything.

CRA considers you a Canadian tax resident until you sever residential ties with Canada. Primary ties: a home available for your use in Canada, a spouse or common-law partner remaining in Canada, dependants remaining in Canada.

Secondary ties - Canadian bank accounts, provincial health card, Canadian driver's licence, professional memberships - support the argument for continued residency if primary ties have not been severed first.

The deemed disposition rule applies on the date you cease Canadian tax residency. CRA treats you as having sold most capital property at fair market value on that date. Gains are taxable. Your principal residence is exempt if you qualify for the principal residence exemption. RRSPs and RRIFs are also exempt from deemed disposition.

Canada and New Zealand have had a tax treaty since 1980, updated in 2012. The treaty prevents double taxation through exemptions and foreign tax credits.

Employment income is taxed in the country where the work is performed. Canadian rental income received by an NZ resident is subject to 25% CRA withholding tax unless a Part I election is made - and must also be declared to IRD. The treaty credit mechanism helps but does not always fully eliminate double exposure, particularly in years where NZ rates exceed what CRA has already withheld.

Provisional tax applies when residual income tax (income not covered by PAYE) exceeds NZD $5,000. It is paid in three instalments during the income year. Late payment attracts use-of-money interest charges from IRD.
