Guest Post: If you rent your property short-term, tell the council and pay your rates
A guest post by James Doolan:
If you own a second property, rent it regularly through Airbnb and have not told your council about the commercial use, this opinion piece is directed at you.
You may regard the omission as harmless or perhaps you’ve realised that the chances of being identified are low. Deliberately withholding information that affects your rates liability is not clever tax planning. It’s gaming the system and leaving other ratepayers to pay more. Kiwiblog readers are usually quick to condemn exactly this behaviour when it occurs in other contexts, particularly when there’s failure to disclose changes in circumstances affecting benefit entitlements.
The obligation to disclose already exists and unambiguous. Section 29 of the Local Government (Rating) Act 2002 requires ratepayers to notify their council when circumstances change in a way that affects information in the rating database, including a change in land use. Councils are required to maintain that database because it determines which rating category applies and how much each property owner pays.
Auckland Council has made the position especially clear. A property rented through Airbnb, Bookabach or a similar platform for more than 28 nights during the relevant rating year may be subject to increased business general rates. Owners are expected to complete a short-term accommodation declaration, even if Council has not contacted them.
This is not a proposed tax. It is the existing law and Auckland’s existing rating policy for short-term rental accommodation (STRA). Basic analysis suggests the change of use disclosure system is not working. It’s costing Auckland Council millions of dollars each year – money that could be spent attracting SailGP or events to Eden Park, something Mayor Brown has long advocated for.
Information obtained via LGOIA requests of Auckland Council showed approximately 505 rating units in its STRA-specific rating categories. AirDNA data, meanwhile, identified more than 4,700 entire-property short-term rental listings across Auckland, along with approximately 1,300 private-room listings.
Those figures might not be perfectly comparable. One property can generate multiple listings, some hosts will fall below Auckland’s thresholds, and no dataset is perfect. Even after making reasonable allowances for those factors, it is difficult to reconcile a market containing several thousand active listings with only a few hundred properties captured in STRA-specific rating categories.
Auckland Council is legally required to maintain a rating information database capable of determining the correct rating treatment for properties. It’s questionable whether that legal obligation is being met.
The financial consequences are significant. For 2025/26, HCA’s analysis calculated Auckland’s approximate urban residential general rate at 0.00225223 per dollar of capital value. The corresponding STRA categories ranged from approximately 0.00303195 for urban medium occupancy to 0.00381167 for urban moderate occupancy. On a property with a capital value of $1 million, correct classification could therefore increase annual general rates by roughly $780 to $1,560 per year.
Using the earlier dataset of 4,777 active listings and subtracting the 505 rating units identified by Council leaves a potential gap of 4,272 properties. Applying the same $780 to $1,560 range across those properties suggests potential under-collection of approximately $3.3 million to $6.7 million annually. The precise figure is impossible to know because Auckland does not have comprehensive visibility of the sector. That, in many respects, is the problem.
The same issue exists with Auckland’s City Centre Targeted Rate. A residential apartment pays a capped charge of just over $75 per year, while a commercially-rated accommodation property with a typical $750,000 capital value would contribute around $990 annually. HCA’s analysis suggests more than 1,200 city-centre STRA properties may sit outside the intended framework, potentially creating another seven-figure funding shortfall. If two physically similar properties are being used to sell overnight accommodation, there should be a very good reason why one contributes more than ten times as much towards the main city centre targeted rate.
There are only a handful of explanations. The market data could be materially wrong. Auckland Council’s records could be materially incomplete. Or a significant number of owners may simply not be disclosing commercial accommodation activity as required. The “rates avoidance” angle gets far too little attention and it’s time to start calling out the hypocrisy of some STRA owners.
Kiwiblog readers tend to be strong supporters of personal responsibility. If somebody receiving a benefit fails to disclose a new income source or a change in circumstances that affects their entitlement, there is usually little sympathy. The same attitude should prevail with people who rent second properties on Airbnb while conveniently skipping past their disclosure and commercial rates obligations.
What is good for the goose should be good for the gander. If we expect honesty and disclosure from beneficiaries, employees and small business operators, we should expect the same from people earning tens of thousands of dollars a year by renting out investment properties and holiday homes through global technology platforms.
This Auckland situation is not unique. That is where a national STRA register enters the discussion.
A cheap national register, funded through a modest annual registration fee, would give councils a practical way to identify commercial accommodation activity without requiring them to trawl Airbnb listings, cross-reference property photos and pursue individual owners one at a time. HCA has consistently argued that councils have a tourism funding problem only in-part because they lack a cost-effective STRA identification tool. A central register solves that problem.
Before councils ask for new funding tools, they should absolutely make better use of the tools they already have, including collecting existing commercial rates and geographic targeted rates.
A national STRA register is not a new tax. It is basic compliance infrastructure. And if your objection is that it might result in a commercially operated property being identified and rated properly, you are not really arguing against bureaucracy. You are arguing for the right to remain below the radar and game the system.This should be the most non-contentious opinion piece ever submitted to Kiwiblog. The call to action comprises two simple and connected next steps: (1) If you rent your property on Airbnb, then declare “change of use” and pay your rates fully if you’re captured by existing bylaws; and (2) Whether or not you’re a landlord, support a simple national STRA register that ensures everyone pays their fair share.
