DHBs are being urged to support GP clinics, that are taking on a greater roll in the Covid-19 vaccine rollout

From Wednesday, the first band of Group 4 -- people aged over 60 -- will start receiving invitations to make their vaccine bookings.

Some general practice clinics will be involved in the roll-out.

The Royal College of General Practitioners medical director Bryan Betty says many general practices have been excluded from administering the vaccine until now.

He says they need the support from DHBs when it comes to vaccine supply and manpower to deal with the workload ahead.
