The committee also considered further advice from the Ministry of Business, Innovation and Employment in response to additional analysis carried out after the bill was introduced. This included proposals which were considered to contribute to the overall aim of mitigating the risk to the Crown or to improve the implementation of the provision. Among others, changes were made to the penalties and enforcement tools and to introduce a penalty for the failure to make payments towards post-decommissioning. This was to make clear that where there was an obligation to do something, we would expect it to be complied with.
