Now, while we recover from the hurt of yesterday's actions, it is still vital to examine how we got here in the first place. The National Party fully supports such a review taking place, and we commit to engaging constructively with it. A review should examine the relationships between the Police and parliamentary authorities and the process through which decisions were taken. It should consider whether communication channels were effective and whether the actions of some authorities—including those of you, Mr Speaker—served to ease the tension or exacerbate it. It should look at the steps that can be taken to mitigate and to prevent situations before they escalate beyond control. We also need a much clearer approach to the management of Parliament's grounds in an environment of elevated risks and threats. A review will undoubtedly find practical measures that can be implemented to enhance the security of this place. However, this Parliament is the heart of our democracy, and it must be open and accessible to New Zealanders. Cloistering and insulating this place and cutting politicians off from the people who elect us and send us here to represent them will only fuel more of the behaviour we've seen, not lessen it. The competing imperatives of safety and public accessibility must continue to be carefully balanced.
