The aim was to prevent nuisance from smell and noise and risks of transferring disease to people.
Six of the former councils in Auckland regulate the type and number of stock kept in town. The former Waitakere City Council does not.
However, the proposed bylaw goes further: it has a new licensing requirement in order to keep six to 12 chickens in Franklin, Manukau, Papakura and Rodney.
The report noted a proposal that keeping more than a dozen chickens in an urban setting could require a resource consent under the Proposed Auckland Unitary Plan.
Animals that come under the definition of stock also include sheep, cattle, pigs, and horses.
Committee member Glenn Wilcox commented that the bylaw might affect a tradition stemming from the country's agricultural heritage.
"We have always had a lamb or calf club - I did not realise we are not allowed to have a lamb."
The report said an alternative to a bylaw would be use of the Health Act to respond to complaints and urgent health problems.
SPCA executive director Bob Kerridge said a number of laws affected the keeping of stock but few people knew about them.
The society would support a bylaw system of licensing that allowed the council to educate people about a minimum standard and to assess the property as being fit for use in size, fencing and drainage. Often people on small lifestyle blocks had "not the faintest idea" of stock needs.
