In the last six months of last year three people were prosecuted for smacking - almost half the total number of prosecutions since the anti-smacking legislation came into effect five years ago.
Police today published their tenth review of smacking-related activity since the introduction of the Crimes (Substituted Section 59) Amendment Act 2007.
The figures covered the period June 22 to December 21, 2011, during which time police attended 500 child assault events.
Of those events, 23 involved smacking and 45 involved "minor acts of physical discipline".
Of the 23 smacking events, three resulted in prosecution; and of the 45 minor acts of physical discipline, six resulted in prosecution.
