Stocks of Covid anti-viral Paxlovid run low

With the country in the grip of a fifth wave of Covid-19, stocks of the Covid anti-viral drug Paxlovid are running low. In a joint statement, Pharmac and Te Whatu Ora say there's limited stock due to higher demand and in some areas including northern New Zealand, pharmacies have temporarily run out of stock. Pharmac says it's working to redistribute supplies and is trying to secure more Paxlovid to arrive in March and April next year.
