Wellington: New Zealand Prime Minister Jacinda Ardern on Monday vowed to unveil reforms to the country's existing gun laws in the wake of the March 15 Christchurch mosques shootings that claimed the lives of 50 people.

At a news conference here, Ardern said her cabinet has agreed "in principle" on proposals to change the country's gun laws in response to the terror attack, but she stopped short of revealing what those changes might be, CNN reported.
