The Government's harshest sentencing rules begin today. Rules like capping the maximum discount that a judge can apply at 40 percent, with some exceptions.

There will be no repeat discounts for youth offenders, those aged 18 to 25. No discounts for remorse, if you're sorry again and again and again, you only get to be sorry once, because Justice Minister Paul Goldsmith said repeat discounts had allowed for lenient sentences.

A new aggravating factor has been introduced for offences against sole charge workers and those whose homes and businesses are interconnected. So basically your corner dairy and that's part of the National-ACT coalition agreement.

A sliding scale for early guilty pleas has been implemented. There's a maximum discount of 25 percent, reduced to a maximum of 5 percent if the guilty plea is entered once the trial has started.

I think there should be a discount for early guilty pleas saving us all the cost of a trial, all for that - but once the trial started and you're playing silly buggars and then decide yeah, I did do it, minimal discount.

The use of cumulative sentencing for offences committed while on bail and custody or on parole will be encouraged to denounce behaviour that indicates a disregard for the criminal justice system, and this was part of the National- NZ First Coalition agreement.

Why have these tougher changes been made? Because that's what New Zealanders in the main wanted. We were fed up with seeing instances like this - a teen mongrel mob member who broke into the home of a pregnant woman, didn't know her, tried to friend her on Facebook, she wasn't having a bar of it - so he broke into her house and indecently assaulted her in the bed she was sharing with her child. This teen (was actually 19), but teen offender was sentenced to 12 months home detention for breaking into her house and for indecently assaulting her in her bed. 

Judge Gordon Matena said he had to hold Stevie Taunoa accountable but also had to take into account his youth at the time of the offending. He noted that Taunoa had spent seven months in custody, had been on electronic monitoring bail since the charges were laid.

He acknowledged that Taunoa had used drugs from a young age and that his offending had been motivated by drug addiction. He also noted his lack of cultural identity and his membership in the Mongrel Mob before sentencing him to 12 months of home detention.  Taunoa said “thank you, judge. I appreciate that”, then laughed like a drain as he entered the police cells and yelled out to all and sundry “cracked it”. All that remorse, eh?

In the meantime, the poor woman said she didn't want to live on her own anymore. She was terrified of the dark, she was terrified to sleep and because of his youth, because he was a druggie, because he lacked cultural identity, because he was a member of the Mongrel Mob, all of that meant that he got his sentence discounted. I was fed up with seeing things stories like this. 

This is only one example. There are hundreds and hundreds. And how can you be sorry 3, 4, 5 times? I'm really sorry. I violently assaulted this person. I'm really sorry I sexually offended. Not once, not twice, not three, four times I'm really sorry. No, no, no, enough.

Again, if the Justice Department could show me that all of these discounts applied to violent offenders to sexual offenders to young offenders, if these discounts meant that they realised they'd had a lucky escape from prison, that this was an opportunity to look at another direction in their lives and take it, if you could show me that it worked I'd be interested in talking. Doubt that you can.

The Government's also looking at longer prison sentences for people who assault prison officers or on duty first responders such as paramedics and firefighters. This is so overdue. The proposals will create a new, specific offence for assaults on first responders.

For those who have family who work on the front line, I know a number of you were terrified about your loved ones going to work. You really hope that you got to see them again, fit and healthy when they came back through the door.

Does this give you a greater degree of security? Probably not, because the offence has to happen before they're punished. But at least, I hope, it gives you the confidence to know that the first responders are valued, that you're recognised. That we know what you do is walk into danger while other people are running away from it.
