Mr Hunter said police were pleased with the behaviour from the majority of drivers at the notorious spot for speedsters.
The wet weather on Monday meant only the speed camera vehicle was used.
Principal of Greenpark School Graeme Lind said speeding outside the school had decreased since 40km/h speed signs were installed outside the school at the beginning of 2010.
The signs are illuminated for 20 minutes during morning and afternoon peaks.
"In general terms the traffic has slowed down and certainly now we are in the winter months they are certainly more visible with the light on," he said.
He said police were often situated outside his school at the beginning of the new term.
"The reason for that is people are coming down from Pyes Pa which is a 60 or 70 area.
"It's just a matter of them remembering all the time to slow down but in general terms I think things have improved." Mr Lind expected traffic flows to continue to increase as more families moved to The Lakes subdivision and Te Maunga. He welcomed the unannounced police presence outside the school.
