Statistics New Zealand has been very clear that they think they are very well positioned to deliver the census in 2023. But notwithstanding that readiness, the external environment—we've noted, in recent years—has a tendency to change rapidly with the ever-evolving COVID-19 pandemic. So I think it's right to have taken a decision to allow for flexibility of timing on the next census in the event that it's happening, should it need to be delayed for some reason or other.
