  • This data is based on purchase claims submitted by DHBs. Pharmac cannot make any guarantee of the accuracy of the figures provided.
  • We have re-exported the data for the financial years provided in our previous OIA response of 16 July 2020. We have also removed the published response from our website. This is because we identified missing data from the previous data released. 

We trust that this information answers your queries. We are making our information more freely available, so we now publish selected OIA responses (excluding personal details) on our website. Please get in touch with us if you have any questions about this. 

Yours sincerely
