Importing American pit bull terriers into New Zealand is outlawed, although they can be bred here.
It is also illegal to import the dogo Argentino, Brazilian fila and Japanese tosa breeds - none of which have been registered or identified in the Lakes district.
Lakes Environmental dog control officers also identified two dangerous dogs - a mastiff and a huntaway Border collie cross, which was classified outside the district as displaying aggressive behaviour, Lakes Environmental regulatory and corporate manager Lee Webster said.
The figure doubles the number of dangerous dogs from one in 2008-09.
Mr Webster said the mastiff was impounded after a "low-level attack" and was found to have "demonstrated behavioural characteristics that were of concern".
No prosecutions arising from dog behaviour were recorded in the period. Attacks recorded ranged in severity from ripped clothing to those that left victims with bite marks.
There were no disqualified or probationary dog owners in the district and the annual report said there were "no issues" with dogs classified as dangerous or menacing.
Dogs under these classifications cannot be taken to any public or private place except when completely confined to a vehicle or a cage.
Dangerous and menacing dogs must also be muzzled in such a way to prevent them from biting, while allowing them to breathe and drink unobstructed.
The report identified that many of the complaints in the general concern category related to dog welfare, such as dogs being left in cold weather, or inside vehicles with the windows up. Several general complaints concerned dogs getting into rubbish and chasing cars.
Infringements jumped from 40 in 2008-09 to 111. Of those, 73 were attributed to owners not registering dogs and most of the remainder (24) were for failing to keep dogs under control.
