Calls for a law change for "humane" slaughtering on farms will force farmers to ensure they have a firearms licence.
The government is looking at introducing a law banning farmers from "bashing calves to death with a hammer or other blunt instrument".
Tracy Amos, vice-president of Wairarapa Deerstalkers, said many farmers in Wairarapa don't have a gun licence to be able to slaughter calves humanely.
She is holding a firearms licence training workshop in conjunction with Masterton police and the NZ Mountain Safety Council for farmers needing to get their licence before the law comes into effect, anyone wanting to learn to shoot or staff at outlets where ammunition or firearms are sold.
Provincial president for Federated Farmers, Jamie Falloon said the proposed law was sensible.
