A growing number of Fresh Zealand motorcyclists are putting their vehicle registrations on hold as part of a coordinated protest against significant ACC levy increases for motorcyclists. The move comes as riders push back against a new pricing structure they claim is unjustified and lacks transparent data, leading some to risk the legal consequences of riding unregistered vehicles.
The dispute centers on a shift in how the Accident Compensation Corporation (ACC) calculates the cost of risk for two-wheeled vehicles. Since July, motorcycles have been categorized into three size-based tiers, with the highest levies falling on larger engines. For many riders, these changes represent a sharp spike in the annual cost of keeping a bike on the road during a period of widespread economic pressure.
From a financial perspective, the new structure moves away from a broader collective pool and toward a more actuarial, risk-aligned model. While the agency argues this is a necessary correction to ensure fairness across all road users, advocacy groups argue that engine displacement is a poor proxy for actual rider risk.
The Cost of the Ride: A Breakdown
Under the current system, levies are collected as part of the standard registration process. The new tiers have created a tiered pricing environment where the cost of ownership varies significantly based on engine capacity and fuel type. All motorcycles are also subject to an additional Waka Kotahi NZ Transport Agency motorcycle safety levy of $25.
| Category | Petrol Levy | Diesel/Electric Levy |
|---|---|---|
| Large (Over 750cc) | $624.93 | $638.36 |
| Medium (251cc to 750cc) | Approx. $450 | Approx. $450 |
| Small (Under 250cc) | $311.70 | $325.13 |
The financial jump is stark when compared to previous years. For example, petrol bikes over 600cc were previously charged $428.19 annually, while diesel or electric models paid $441.87. For those with mid-sized bikes, such as a 500cc model, the cost in the 2024/2025 year was just under $300. Richard Tohu, a spokesperson for the Motorcycle Advocacy Group, notes that the total cost of registration is on track to increase by 68% by 2026.
To mitigate these costs, riders who have completed advanced rider training may be eligible for a 25% discount, a move intended to incentivize safer riding habits through financial relief.
‘Indicate Us the Data’: The Advocacy Pushback
The protest has gained significant momentum online, with a dedicated Facebook group growing from 5,000 to nearly 9,000 members following a protest ride on the 28th. The core of the grievance is not merely the cost, but the perceived lack of transparency regarding the data used to justify the hikes.
“It’s just a lot of money. Everybody is feeling the crunch and they can’t justify the increases,” Tohu said. He emphasized that the group is not seeking a free ride, but rather a justification for the pricing. “We all know the bigger the engine does not equal higher risk… Show us the data.”
The Motorcycle Advocacy Group has requested meetings with officials to review the risk data, but those requests have reportedly gone unanswered. In response, the group is advising members to put their registrations on hold to force the agency to the negotiating table.
This strategy carries inherent legal risks. While putting a registration “on hold” legally means the vehicle cannot be driven, there are concerns that some riders will continue to use their bikes. The penalty for riding an unregistered vehicle is a $200 fine plus demerit points. Tohu acknowledged that for some, the risk of a fine is more palatable than paying a $600 registration fee, though he clarified that the group does not condone illegal riding.
The Actuarial Argument: Subsidies and Risk
ACC maintains that the ACC levy increases for motorcyclists are a matter of fundamental fairness to the wider tax-paying public. Stewart McRobie, ACC deputy chief executive of corporate and finance, argues that the motorcycle community has been heavily subsidized by other road users for a decade.
According to ACC, the lifetime cost of motorcycle injuries is estimated at approximately $266 million per year in the current cycle. The agency points to a significant disparity between fleet size and cost: while motorcycles make up only 4% of the vehicle fleet, they account for 25% of the total cost to ACC for all road crash injuries.
Currently, motorcycle owners pay 28% of the costs associated with their own accidents, meaning the remaining 72% is subsidized by levies collected from passenger cars and other vehicles. McRobie noted that levies for motorcyclists had not increased since 2014, making the current adjustments a long-overdue correction.
The agency is also focusing on “single-vehicle accidents”—crashes where no other vehicle is involved and the rider’s actions contributed to the event. Police data indicates that 37% of injury claims from motorcyclists fall into this category. By increasing the levies, ACC aims to align the financial contribution of motorcyclists with the actual proportion of these single-vehicle crashes.
Market Impact and Registration Trends
The tension between riders and regulators may already be reflecting in national registration data. NZTA figures show a 9.8% decrease in first-time motorcycle registrations between the March 2025 year and March 2026. This decline stands in contrast to the passenger car market, which saw a 2.7% increase in registrations over the same period.
While these figures reflect new entries into the market rather than existing owners, they suggest a potential cooling of interest in motorcycle ownership as the cost of entry and maintenance rises.

The current levy round covers the period from 2025 to 2028. The next official review of these levies will determine if the risk-based model successfully reduces injury costs or if the financial burden continues to drive riders away from the road. We will continue to monitor for any official responses from ACC regarding the request for data transparency.
