Police expect a high number of people have been caught using their cellphones while driving during a 10-day blitz and are not ruling out another crackdown.
Police carried out a nationwide crackdown, starting on October 25, to catch people breaking the two-year-old law.
Acting Road Policing Manager Inspector Rob Morgan said information from officers suggests figures will be high, but it will be one to two weeks before the official numbers will be ready.
He said an increasing number of people had been caught using their cellphones over the April to June period this year.
Police figures showed 15,000 offence notices had been issued nationwide over the past two years for using cellphones while driving, and more than 900 people were ticketed in August and September in normal policing conditions.
