"It is anticipated sales of utes will gradually recover as the year progresses."
The Clean Car Discount, or "feebate" scheme, charges fees on imported cars of up to $5175, money which is then used to subsidise discounts of up to $8625 for people buying EVs, hybrids and other low-polluting cars.
Crawford said, as expected, it was the weakest month of April since 2015.
"With the weak sales of utes for the month, not surprisingly the top spots for April 2022 went to passenger and SUV segments, with the small to medium segments accounting for 78 per cent of April registrations."
Last month, 572 pure electric vehicles, 1113 plug-in hybrid electric vehicles (PHEVs) and 2145 hybrid vehicles were sold.
For April, the top three models were Mitsubishi Outlander (837 units), followed by the Toyota RAV4 (716 units) with the Mitsubishi Eclipse Cross in third place (544 units).
