Hon CHRIS HIPKINS: In the way the vaccine roll-out has been scaled up, we have been focused on making sure that we honour all bookings in the booking system. What we may find ourselves in the position of doing is, if we cannot increase supply in the next five or six weeks, we may find ourselves having to restrict ourselves to those vaccines that have been booked, and scale back some of the additional capacity that's being brought online over the last few weeks.
