Resource Management penalties regime enters new era
A well-publicised change under the August 2025 amendments to the Resource Management Act 1991 (RMA) is the significant increase in maximum fines – from $200,000 to $1,000,000 for individuals, and $600,000 to $10,000,000 for corporates.
Were we entering the era of million-dollar RMA penalties?
There is a delay between legislative change and new penalties being imposed, as offences are sentenced under the penalties regime in place at the time offending occurs. The question of how high fines would actually go under the August 2025 amendments has been left hanging - until last month, when the Environment Court considered the new regime in Waikato Regional Council v Clarke. In this article we dive into the decision.
Waikato Regional Council v Clarke
In Waikato Regional Council v Clarke, Mr Clarke was sentenced on one charge of discharging a contaminant, namely effluent, onto land in circumstances where it may enter water. The offending occurred on 2 September 2025, some 12 days after the new RMA penalties regime came into force.
When considering an appropriate penalty, the prosecutor submitted that the uplift in RMA fines imposed under the new regime should be significant. This submission was based on similar approaches to penalty uplift in a health and safety context. In Stumpmaster v WorkSafe New Zealand [2018] NZHC 2020, the High Court considered the appropriate penalty where maximum fines under the Health and Safety in Employment Act 1992 (HSEA) had been uplifted through legislation reform, from $250,000 to $1,500,000. Penalties under the HSEA are imposed under structured sentencing bands or ranges, where the appropriate penalty band is determined in relation to the seriousness of the offence, with the bands themselves established through guidance judgements. In Stumpmaster, reflecting the uplift in maximum penalty, the Court set new higher ranges for the four penalty bands, starting at $250,000 and reaching to $1,000,000+ for serious offending.
RMA sentencing has not historically relied on guidance judgements when setting penalties in the same way that HSEA does. Sentencing under the RMA does draw some guidance from the bands outlined in Waikato Regional Council v GA & BG Chick Ltd (the Chick bands). The Court in Chick found that penalties historically imposed under the RMA could be divided into three bands derived from features of the offending, being:
Level 1 – generally an unintentional, isolated incident with little or no environmental effect;
Level 2 – generally careless or recurring discharges with little to moderate effect; and
Level 3 – deliberate offending or offending involving a real want of care.
However, the Chick decision is a survey judgement, being one which reviews and summarises historical decisions, rather than a guidance judgement like Stumpmaster. Further, the quantum of the Chick bands was set in 2007, and is generally considered to be out of step with current RMA penalties.
Appropriate penalty setting under the RMA is therefore guided by Chick along with other considerations such as the offender’s culpability, precautions taken to prevent discharges, the vulnerability or ecological importance of the affected environment, the extent of the environmental damage, deterrence, the offender’s capacity to pay a fine, disregard for abatement notices or council requirements, and cooperation with enforcement authorities and guilty pleas (as summarised in Thurston v Manawatu Wanganui Regional Council HC Palmerston North CRI-2009-454-24, -25, -27, 27 August 2010).
Relying on the uplifts under the HSEA caselaw, the prosecutor in Clarke submitted that the RMA amendments meant the Chick bands fine ranges should be uplifted, to $50,000-$200,000 for Level 1, $175,000-$500,000 for Level 2 and $450,000-$1,000,000 for Level 3.
The Court was not convinced, however, that a sudden uplift in RMA penalties was required, preferring an approach where the uplifts develop over time. The Court noted that:
78] When Chick was decided, the Court could identify a pattern from sentences already imposed. There are not yet sentencing decisions under the amended regime from which to derive equivalent new ranges. Prescribing them now would be premature and might unnecessarily restrict the Court\'s responses as that case-law develops.
[79] Further, it is not necessary to create new levels of culpability. Chick’s descriptions remain flexible, while its historical fine ranges need not be followed.
…[116] The Court needs to take care to ensure that a fair and consistent approach to sentencing occurs, and one of the means by which that can be achieved is by allowing the approach to develop. That is not to say that I ignore the new maximum penalties; rather that I find that sentencing is not a tick box exercise undertaken with maximum penalties top of mind. It is a more rounded exercise involving all the matters to which the Court is required to have regard to under the Sentencing Act and as helpfully summarised by the High Court in Thurston.
The Court determined the offending in Clarke to be “well within” Chick level 2, and adopted a starting point of $130,000. Relevantly, the Court noted “If it assists the parties, I record that if the legislation had not been amended I would have likely adopted a starting point of $85,000.”
What does Waikato Regional Council v Clarke mean for RMA penalties?
The penalty starting point in Clarke was approximately a third higher than would have been imposed under the old regime. The author notes that the starting point for mid Chick Level 2 offending would have been $337,500 if the prosecutor\'s proposed new “sudden uplift” bands had been accepted.
The Court\'s sentence in Clarke indicates that, under the new penalties regime, RMA penalties are likely to increase gradually over time towards the top end of new penalties, as opposed to suddenly jumping nearer the maximum.
A gradual increase in penalties is consistent with historical patterns of RMA penalty increase. A study undertaken by Andrew Franklett and published in the August 2025 Resource Management Journal looked at penalties imposed between 2000 and 2025. Analysis of sentencing decisions concerning discharges to water showed a steady increase over time (bar some outliers which dragged the average penalty up in some years), as shown below:

Notable is that after the last significant statutory uplift in RMA penalties in 2009, rather than there being a sharp uplift in penalties imposed, the steady rise continued. Clarke appears to indicate the Court’s desire to continue on this gradual upward trajectory, noting that some uplift above pre-August 2025 penalties attributable to the legislative change can be expected going forward.
