The defence has challenged the accuracy of the prosecution's expert witness testimony about where he places the victim of an alleged hit-and-run and the speed of the vehicle before impact.

Raymond Green, 33, on trial in the High Court at Tauranga, has denied one count of murder. He is accused of mowing down 33-year-old Ilya Olegovich Kojevnikov in Welcome Bay Rd on February 2, 2015, as the deceased was walking along the road.

The Crown's expert witness, Dr Ian Calhaem, qualified in video analysis, has calculated the speed of the vehicle travelling back down the road was 1.5 times faster than it had travelled up the road.

Dr Calhaem said he had analysed the video footage captured by three CCTV security cameras at the Welcome Bay Foodmarket.

The witness earlier told the jury that before braking he had calculated the vehicle's velocity at an average of about 100km/h using a frame by frame analysis of the video footage.

Dr Calhaem said from his analysis the driver-side wheels came within the median strip on its return journey, and the victim's feet could be seen on the edge of the median strip. Yesterday Green's lawyer, Tony Rickard-Simms, put it to Dr Ian Calhaem that he could not say with any certainty the speed of the vehicle, nor the position of the feet of the deceased.

"It's completely misleading for you to say to the jury you can make assumptions about the speed the car was going when you can't see it."

Mr Rickard-Simms put to Dr Calhaem there were so many other variables that needed to be taken into account, that included what the victim and the accused would have each seen.

The prosecution closed its case last night.
