Madam Speaker, I thank my colleague for her relevant question.
I looked at the figures and statistics provided by the New Zealand government on the number of weapons recovered by authorities. I have already mentioned the work of Professor Philip Alpers of the University of Sydney, in Australia, an expert in the field, who has studied the differences between voluntary and mandatory buyback programs to demonstrate how well they have worked.
As I said earlier, collecting hundreds of thousands of weapons rather than none at all is in itself indicative of the program's success.
