The Government's first purchase order of the Pfizer vaccine comprised just 54,600 doses, and was made in late January, despite a commitment from Covid-19 Recovery Minister Chris Hipkins that New Zealand would be at the "front of the queue" for jabs.
In October, the Government signed an advanced purchase agreement for 1.5 million doses of Pfizer's vaccine, the jab that would later form the backbone of the vaccine rollout.
As part of the deal, no vaccine would be shipped until Medsafe had given approval of the vaccine. For a medicine or vaccine to be imported into New Zealand, it must have Medsafe approval.
When approval was imminent, the Government could raise a purchase order with Pfizer who would then deliver the vaccines.
On January 29, days before Pfizer's jab was given provisional Medsafe approval, the Government made a purchase order for 56 trays of the vaccine, amounting to 54,600 doses. As it transpired, those trays stretched to 65,520 doses, when it was discovered six doses could be extracted from a single vial, rather than five.
