A policy decision was made in 2009 to suspend contributions to the New Zealand Superannuation Fund in the wake of the global financial crisis. A number of decisions—there were some criteria set for when they would be restarted. There were two, but one of those was when the books of the Government returned to surplus. Unfortunately, that did not occur, and so on coming into Government at the end of 2017, we took the decision to restart contributions immediately. We have since that time stayed ahead of the formula in order to try to make up the difference of some billions of dollars that were not put in, and so in this current fiscal year, we're putting in twice the contribution required by the legislated formula: $2.4 billion versus $1.2 billion.
