More than three-quarters of people are keen to get the Covid-19 jab, according to a survey conducted by the Ministry of Health.

Since the last survey in March, the proportion of people over the age of 16 willing to get the vaccine increased from 69 per cent to 77 per cent.

The number of people saying they're unlikely to get vaccinated has also dropped from 20 per cent down to 12 per cent, says Covid-19 Response Minister Chris Hipkins.

Meanwhile some experts are calling for the national contact tracing system to be ramped up in case there is another mass community outbreak. University of Otago professor Philip Hill and Sir Brian Roche, who is chairing a review of the pandemic response, have doubts the current system could cope with tracing more than 200 cases a day.

On Friday, there were no new cases in the community to report, and three cases in managed isolation.

After positive wastewater samples were identified in Wellington, Christchurch, Rotorua and Queenstown earlier in the week, further tests in Rotorua have come back negative.

Global toll

Globally, Covid-19 cases have surpassed 165.6 million, according to data from Johns Hopkins University.

Global deaths have exceeded 3.43 million, and more than 1.59 billion doses of vaccine have been administered.

The United States has still recorded the most Covid-19 cases in the world with 33 million and 588,859 deaths. India's harrowing second wave of infections continues to drive numbers up with 26.03 million cases and 291,331 deaths reported.

Taiwan, where the virus was contained quickly early in the pandemic, is experiencing a growing outbreak. This week alone, more than 1400 new infections and three Covid-related deaths have been reported. For the first time since the pandemic began, nationwide restrictions have been imposed to curb the spread of the virus.
