The Sentencing and Parole Reform Act came into force on June 1, 2010 and creates a three stage regime of increasing consequences for repeat serious violence offenders.
According to the Ministry of Justice's website, since the law came into force 114 offenders convicted in Tauranga District Court have received their first warning.
Last year 61 people convicted in the same court received first-strike warnings and eight so far this year, while nationally by the end of last month 2684 people were on their first warnings.
A spokesman for Justice Minister Judith Collins said the case highlighted that the three-strikes legislation was "working well".
Ken Evans, spokesman for the Tauranga arm of the Sensible Sentencing Trust, agreed.
"The Trust believes the law is working and shows recidivist criminals they will not just get out after serving part of their sentence like the previous crazy parole system did."
Mr Evans said the community would be far safer now Tukaki was behind bars.
Last month Hastings man Elijah Akeem Whaanga, 21, was jailed for two-and-half years without parole for two street muggings in August last year, and received his final three-strikes warning, his first warning was in December 2010 for aggravated robbery.
