"They see all sorts of issues."
He understood cost was a major factor, particularly for vehicles with a larger battery.
These factors were highlighted in recent research commissioned by Great South.
However, the results of surveys have the agency saying barriers can be overcome.
Great South strategic projects general manager Steve Canny previously told the Otago Daily Times the Southland EV ownership rate sat at 0.75 vehicles per 1000 people.
Only Gisborne and the West Coast had lower rates than Southland.
Auckland's rate was 6.9 per 1000, Wellington's was six per 1000, Canterbury's was 5.75 per 1000 and Otago's sat at 4.14 per 1000. The study updated the figure to 0.67 vehicles per 1000 people for Southland.
A total of 1000 survey responses were received, 75 per cent of those being from individuals, while 25 per cent were from self-employed people or businesses.
Canny said business respondents further noted towing ability and the need for off-road vehicle options as barriers to getting an EV, but noted farm bikes and side-by-side utility terrain vehicles were already available in Southland and their use was increasing.
The Government is encouraging a move to EVs as part of its drive towards a net-zero emissions economy, and partway through the survey collection announced a rebate scheme to encourage EV purchase.
From 2022, it is proposed high-emitting vehicles be charged a levy to cover the subsidy.
Overall, 74 per cent of business and 46 per cent of households were not supportive, with a large number undecided, the survey showed.
"Most significantly, the announcement of the clean-car subsidy reduced the likelihood that Southlanders would purchase an EV or hybrid vehicle. This was even the case for those within the subset respondents with strong support for climate change action," Canny said.
Great South supposed the decrease in likely EV or hybrid uptake was due to a change in the type of people who answered the survey after the announcement.
But it figured this would mean the overall survey would more accurately represent the views of the Southland population as a whole.
Great South planned to use the findings to develop projects to address and overcome the key barriers and concerns.
