As of Monday, 53,000 calls had been taken by 105 operators.
A police spokeswoman said the number was being "widely used" for a variety of non-emergency situations including thefts from public places and cars, intentional damage to property, shoplifting and lost property.
Of the calls being made, 14 per cent relate to matters previously reported to police.
A further 21 per cent are from people seeking advice from police.
"Since we've launched the marketing campaign and the 105 jingle, we're seeing daily increases in the number of people calling 105 to report non-emergencies, rather than other channels," the spokeswoman said.
One of those other channels is the option for people to report some specific non-emergency situations online.
The online reporting facility was launched late last year and each week since then, about 800 reports had been filed.
Bush urged people to use the online service where possible.
Since the 105 service was launched, police have been seeking feedback for users.
According to the spokeswoman, 90 per cent of callers were satisfied with the quality of the service and 94 per cent were likely to call 105 again if needed.
"67 per cent of people are aware that we have launched a new non-emergency number," she said.
