Public willingness to get the Covid-19 vaccine is at its highest level ever, according to new survey results that suggest four out of five Kiwis either intend to get the shot or likely will.
New data collected from a survey of nearly 1100 people found that, as atMay, 67 per cent of respondents would "definitely" get the vaccine – up six per cent from two months earlier.
The research, overseen by Massey University communications lecturer Dr Jagadish Thaker, also found 16 per cent were unsure but leaning toward receiving it.

The data also showed that slightly fewer people answered "unsure, but leaning toward no" in May (10 per cent) than March (12 per cent) – a change that reflected more people being still unsure but now leaning toward "yes".
The proportion of people who said they definitely wouldn't get the vaccine remained steady at around one in 10.

An analysis of differences across ethnicities found 68 per cent of Pakeha "definitely" wanted to be vaccinated, up 4 per cent on March's figures, as did 54 per cent of Māori (up 10 per cent) and 72 per cent of Asians (up 13 per cent).
There was also an increase in general willingness across gender – rising to 71 per cent of men and 62 per cent of women, up from 66 per cent and 55 per cent respectively – as well as across people with all measured levels of education.
The overall trend was in line with the Ministry of Health's own research, which had found the potential uptake had increased from 69 per cent in March to 80 per cent in May.
But the research also carried some concerning insights.
Fewer than a third (27 per cent) had either "often" or "very often" heard or read the Government's Covid-19 vaccination communication campaign on radio, in newspapers or on social media – and just four in 10 had come across it often on TV.
That could indicate a missed opportunity, given the data also found that nearly a third of people who were hesitant or sceptical – up from 18 per cent in March - said more information from the Government could help them change their minds.
Among those people who wanted more information from the Government, watching this video was shown to steer some more toward getting the vaccine.
"The more we can show these people these videos, especially among the hesitant, the more likely it'll be that they change their intentions."
Modelling by Te Pūnaha Matatini researchers has indicated that 83 per cent of Kiwis would need to be vaccinated against less transmissible virus strains, like the original wild type, for measures like lockdowns and 14-day quarantine to be no longer needed.
And as much as 97 per cent of the population would need both Pfizer shots to abandon such measures, the modelling suggested, if the country was hit by a wave of a strain as transmissible as the delta variant.
However, University of Auckland vaccinologist Associate Professor Helen Petousis-Harris said there was still no "magic number" of uptake to achieve population immunity, which depended on a range of factors.
Nonetheless, Petousis-Harris was encouraged by the latest survey data, which she said reflected a growing trust in vaccine safety, and people seeing others receive the shot with few issues.
"If we have a highly vaccinated population, it will just get easier to contain this virus," Otago University epidemiologist Professor Michael Baker added.
"And then, at a certain point, we'll be able to look at what the evidence is showing, and decide – and this is the big question – what our ultimate strategy is."
