Companion Animals Act 1998 No 87
Current version for 5 December 2019 to date (accessed 6 August 2020 at 05:44)
Part 2 Section 10
10   Regulations may require registration
The regulations may require a particular class or description of companion animals (not otherwise required to be registered) to be registered. The owner of such an animal is guilty of an offence if it is not registered.
Maximum penalty—
(a)  in the case of a dangerous, menacing or restricted dog—60 penalty units for a first offence or 70 penalty units for a second or subsequent offence, or
(b)  in any other case—50 penalty units for a first offence or 60 penalty units for a second or subsequent offence.
Note.
 For example, the regulations could require that a companion animal be registered if it has been seized under this Act (for example, because it was found at large outside the property of its owner). The animal would then have to be registered even though it might be less than 6 months old.
