More than 6500 people have been ticketed for hand-held cellphone use while driving since a ban on such use came in almost a year ago.
Figures show the number of drivers fined $80 and given 20 demerit points for breaking the ban on using hand-held cellphones has gradually risen from about 450 a month in the first few months to 834 in August.
Provisional data for September, the 11th month of the ban, pits ticket numbers at 429, though police expect that to rise to about 600.
Including the provisional September data, 6586 tickets have been issued.
Acting Road Policing Manager Rob Morgan says while the public has by and large responded well to the road rule, some drivers appear to be slipping back into old habits.
But he says police will continue to fine anyone they catch breaking the cellphone rule.
Automobile Association motoring affairs general manager Mike Noon says it is concerning so many drivers are continuing to flout the rules.
He says to improve road safety further drivers need to get to a point where it is an automatic response not to use a hand-held cellphone.
