CHRISTCHURCH, New Zealand — When the prime minister announced plans to ban semiautomatic rifles following Friday’s mass shootings, it seemed to be the bold response that many New Zealanders wanted — until the country’s attorney general backpedaled almost immediately and said that might not be the government’s final decision.

Even after a massacre that left 50 people dead, the fight over guns and safety will be a fraught one for politicians in peaceful New Zealand, just as it is in the United States.

But there is a crucial difference between the two countries that is already apparent: While Washington struggles to take action even as such shootings become more routine, New Zealand’s government is immediately diving into a detailed discussion of further legislative checks on guns.

The outright prohibition of semiautomatic weapons proposed by Prime Minister Jacinda Ardern may no longer be on the near-term table. But she’s made clear that lawmakers will look at a range of options, from gun buybacks to restrictions on magazines for semiautomatic rifles.
