Gun Control advocates are calling for an end to firearms advertising to help stem gun violence.
A 32-year-old man was shot and critically injured by police in the Auckland suburb of Grey Lynn on Monday evening, after shooting up his own house and then turning his gun on police.
Gun Control New Zealand spokesperson Hera Cook says there are anywhere between 1.2 and 1.7 million guns in the country, and it's easy enough for unlicenced individuals to get their hands on one.
She spoke to Kim Hill.
