"A Modest but Tangible Success" - aka, "Abject Failure"

New Zealand's "buyback" is going pretty much as expected - with a projected compliance of less than 30%:

New Zealand Police Minister Stuart Nash announced this week that more than 32,000 prohibited weapons have been returned to the government since collections began in mid-July. Some estimates put the number of newly-banned military-style semi-automatic rifles in the country at up to 175,000.

This would suggest a compliance rate, so far, as low as 18 percent, 16 weeks into the buyback program. With seven weeks left to go until the amnesty period ends, if the current rate of return holds, the New Zealand government is on track to collect around 50,000 prohibited weapons pursuant to the buyback. That would impute a final compliance rate of around 29 percent, at the lower end, which would represent a modest but tangible success for policymakers.

"Owning a firearm is a privilege not a right," New Zealand Prime Minister Jacinda Ardern said in September as the country's parliament considered new gun control laws.
