Why is this happening?

This is a tender brand change. Every year, Pharmac runs a tender process to create competition among suppliers to supply many medicines used by New Zealanders.

The tender helps Pharmac manage the costs of medicines. Any savings we make are returned to the medicines budget to help pay for new medicines.

Your brand change is helping fund more medicines for more New Zealanders.
