New Zealand has launched a gun buy-back scheme in the wake of the deadly Christchurch mosque shootings.
More than $208m New Zealand dollars (£108m, $136m), have been set aside to compensate owners of semi-automatic weapons which were banned following the attacks.
The ban was agreed by parliament in April, weeks after the shootings.
In March, a gunman killed 51 people at a mosque and Islamic centre during Friday prayers.
