A woman in a purple jacket attempts to help the ducks across the road, going into the middle of the lane and then walking back to the side.
She can be seen gesticulating to the driver of the red-coloured 1996 Subaru Legacy as it approaches to slow down, but the car does not appear to, driving over several of the ducks, while the woman stands just off the footpath.
Liechti said the mother and one of the ducklings were killed ''so that means they're all dead now, probably''.
''Right behind [the car] you can see there's a school sign, 'Slow for Children', and you can see the woman is right out in the road in her big purple coat ... it was obvious.
''Whenever we see them [ducks] we always stop the traffic and help them across the road ... everyone does ... because they go across the road to the creek.
''We even had signs up there last year after someone ran over them, but this guy just didn't even seem to give a s..., either that or he was on the phone or something or wasn't looking, who knows.
''It just didn't seem right - if someone's out there stopping ducks, you think you'd stop.''
He called police to report the incident that day, but says he was instructed to ''do it online''.
He had not heard anything further, he said.
A police media spokeswoman confirmed a complaint had been received about 5pm on October 10 reporting a driver ''driving dangerously and could've hit a lady and some ducks'' earlier that afternoon.
''The information provided during the call did not indicate that any offence had been committed or that anyone had been injured,'' the spokeswoman said.
''It didn't appear from the information provided during that call that an offence had been committed so no further action was taken.''
Liechti sent the footage to the Otago Daily Times after reading about two police officers in Dunedin who escorted a mother and her ducklings to safety on State Highway 1 by Green Island last Thursday.
''I saw the big hoo-hah in the Otago Daily about the cops putting on their lights and sirens and heading off to help some ducks cross the road [in Dunedin] and in Queenstown, when it happens, they weren't even interested.''
