Nearly 12,000 people suffered dog bite injuries last year, including more than 1700 children aged under 10 - many of whom will be left with scars.
The number of attacks requiring medical attention has increased since 2003 when 8677 people were attacked, including 7-year-old Carolina Anderson who has needed years of surgery after being mauled in an Auckland park.
Her case was so bad it resulted in tougher dog control measures being passed, including the compulsory microchipping of all dogs, but they appear to have done little to prevent thousands of other children from being bitten.
More than $3 million of ACC money was lost to fraud last year and culprits increasingly include widowed women ripping off the system.
Nearly 100 people have been prosecuted for fraud since 2007 and figures released to the Herald under the Official Information Act reveal the total savings to the taxpayer from the detection of last year's fraud alone was $37 million.
Although the total amount of fraud in the 2010/11 fiscal year was $3.1 million, the higher figure of $37 million is reached when the impact the fraud would have had on taxpayers if it was not discovered was taken into account.
