Hawzah News Agency - (Christchurch - New Zealand) - New Zealand's new gun restrictions do not go far enough and should ban the type of bullets used in the mosque shootings, Christchurch mayor Lianne Dalziel says.

The nearly 100 victims shot in the March 15 attacks were struck by a type of expanding bullet designed to do maximum damage inside a body.

However, hunters using the ammunition to shoot animals say there is no humane alternative.

A ban introduced last month, which will need to be confirmed by legislation within a year, bans military ammunition such as incendiary, explosive, armour piercing and tracer bullets. It follows the tighter gun laws banning military style semi-automatics and assault rifles introduced in April.

"He [the gunman] used soft-nosed bullets that caused incredible damage," she told The Guardian newspaper.

"They are designed to do great damage and they did."

Following the attacks, medical staff at Christchurch Hospital revealed the extensive damage done to the victims. Surgeon James McKay described how the bullets had ricocheted internally and damaged organs not in their path.
