The assessor is calling for technology such as autonomous emergency braking to become standard features on all new vehicles.
Among the new showroom entrants wearing five-star ratings are the Jeep Cherokee, Skoda Rapid, Honda Odyssey and Nissan Pathfinder Hybrid.
Set to be launched next month, the Cherokee is the first Jeep rated by Ancap to achieve all five safety stars.
"Jeep is a mainstream brand that has been around for many years but has lagged its competitors in terms of safety," Mr McIntosh said.
The Cherokee is fitted with a full suite of airbags and a number of safety assist technologies including
roll stability, trailer stability, tyre pressure monitoring and daytime running lights as standard on all variants.
Autonomous emergency braking, radar cruise control, blind-spot monitoring, reversing collision avoidance and lane support systems are available only as added options on more expensive variants.
It's a similar situation for the Skoda Rapid, Honda Odyssey and Nissan Pathfinder Hybrid.
"While each of the cars for which we've released ratings have achieved excellent results and provide a very high level of safety for occupants -- and, in the case of the Cherokee, Odyssey and Pathfinder, have increased their ratings from previous models -- there now needs to be a shift in focus [towards additional safety assist features]," Mr McIntosh said.
