What this page is

ProppiAI publishes research, guides, and reference content about property intelligence for landlords, investors, and property managers in New Zealand and Australia. Because tax and tenancy rules differ between the two countries — and differ again between Australian states — accuracy matters more than speed. This page explains the rules we hold ourselves to.

Sourcing

Every factual claim on this site — a tax rate, a notice period, a compliance deadline, a legal threshold — is traceable to a primary source. We prioritise, in this order:

1. The Act, regulation, or ruling itself, on an official government site.
2. The relevant government body's published guidance.
3. A peer-reviewed or professional-body publication.

Our standard primary sources include:

• New Zealand tax: Inland Revenue (ird.govt.nz), legislation.govt.nz (Income Tax Act 2007, Tax Administration Act 1994).
• New Zealand tenancy: Tenancy Services (tenancy.govt.nz), Ministry of Business, Innovation & Employment (MBIE), the Residential Tenancies Act 1986, Healthy Homes Standards regulations.
• Australian federal tax: Australian Taxation Office (ato.gov.au), legislation.gov.au, ATO public rulings and taxation determinations.
• Australian tenancy and property taxes: the relevant state or territory body — Fair Trading NSW, Consumer Affairs Victoria, Residential Tenancies Authority (Queensland), Consumer and Business Services (South Australia), Department of Mines, Industry Regulation and Safety (Western Australia), Consumer, Building and Occupational Services (Tasmania), Access Canberra (ACT), and Consumer Affairs (NT) — plus each state's revenue office for stamp duty and land tax.

If we can't find a primary source for a claim, the claim doesn't get published.

Region specificity

Australian federal tax rules (capital gains tax, negative gearing, depreciation) apply nationally, but tenancy law, stamp duty, land tax, bond lodgement, and first-home grants all differ by state or territory. We never write "Australian landlords must..." without either (a) naming the specific state the rule applies to, or (b) citing the federal law that governs the claim. Blanket claims about "Australia" on state-regulated topics are almost always wrong, and we treat them as factual errors.

The same specificity applies to New Zealand — we cite the Act and section (for example, "Residential Tenancies Act 1986 section 45") rather than handwaving about "the tenancy law".

ProppiAI's own data

Some of our research pages cite statistics derived from documents ingested via ProppiAI. When we do, we label those numbers clearly as ProppiAI measurements (not market-wide statistics), disclose the sample size and date range, describe the methodology, and note known limitations. A sample that is too small to support a conclusion is reported as such, never aggregated into a misleading headline.

Fact-checking before publish

Every article goes through the following checks before it is published:

• Every statistic is re-derived from the source data or re-checked against the cited source.
• Every legal or tax claim links to a primary source on an official site.
• Every region-specific claim names the country — and, for Australia, the relevant state or federal law.
• Every pricing claim matches the current pricing on our pricing page, exactly.
• Every page has a visible publication date, and research pages show when they were last reviewed.

Corrections

If you spot an error — a stale rate, an outdated deadline, a misattributed source, or a region claim that should have named a state — please contact us. When we correct an article, we update its modification date and, when the change is material, add a short note explaining what changed.
