So, look, for the purposes of just illustrating why we think it's important, there are a number of different options that Government has for increasing the protection of retentions held by contractors and subcontractors, protecting them from their client—the largest client in New Zealand right now being the New Zealand Government and local councils. They are most likely to be responsible for making it more difficult for contractors and subcontractors to recover retentions, any minor defect that has to be disputed with a trustee, who may themselves feel some significant responsibility not to release retentions from a trust until all of the client's obligations are met. Often, clients and main contractors can be far more lenient and relaxed about releasing retentions at the end of a contract period or a defects period if they can be sure that the issue is no more than minor or that it has no impact on the design intent and the performance of the new asset.
