The story that has made the front page of the Herald this morning and dominated the conversation was the leadership of Prime Minister Christopher Luxon. He is facing what party insiders describe as “the most difficult fortnight of his leadership”, with growing speculation about his support within National's caucus as Parliament returns next week. Sources say that the whip, Stuart Smith, tried to present Christopher Luxon with evidence that caucus backing for his leadership had weakened. He tried to do that before Easter, but Christopher Luxon did not want to hear this. They did not have the meeting. It's understood those who believe Luxon should step aside might act in the next two weeks, although a formal leadership challenge or confidence vote is still seen as unlikely. Instead, the preferred option amongst critics appears to be having a good old chat with Christopher Luxon with evidence of his diminished support within his caucus, and that might prompt him to resign or step aside and bring about a change of leader. Now, if that doesn't happen, a challenge could follow, but there's no declared challenger at this stage.

All of this is at a critical time. Parliament's back for a short sitting block before recessing again ahead of the Budget. Here comes the Budget. Political analysts say removing a Prime Minister during the Budget period risks destabilising the Government. So it's this next fortnight or not, because after that we're into Budget time and that would be even worse for National.

National Minister Chris Bishop, who has been widely rumoured as a potential contender, was on the radio with Mike Hosking this morning. He came on to talk about the changes to the Warrants of Fitness, but instead he got a little surprise of talk of a coup. Chris Bishop described the situation as “untidy and unhelpful”. He said there's no leadership challenge underway, and he said he will not be the National leader before the election. But the general consensus to that interview was that he was being a little shifty, and he knows a lot more than he was letting on. How could he not know the feeling in the caucus? He's around there the whole time. How could he not know that three guys had actually come to Thomas Coughlan? But he claimed he didn't.

Furthermore, can I just remind you that Chris Bishop is scheduled for an interview with Jack Tame on Q&A on Sunday, so you know this issue is going to continue bubbling away. Behind the scenes, tensions were already evident before Parliament recessed. We reported, everybody reported, that Christopher Luxon faced pressure from within caucus during the final sitting week and he ended up reshuffling the party, hopefully to stabilise it, but look at this, it's still rumbling on. When party whip Stuart Smith got ghosted by Christopher Luxon, he ended up raising all his concerns with deputy leader Nicola Willis instead. We've got a poll out right now and those numbers are adding to the pressure. National is currently sitting well below Labour and another major poll is due next week. So, all eyes are now on the coming days and how Christopher Luxon and his senior colleagues respond.

Bunnings have begun rolling out facial recognition technology in its New Zealand stores, saying it's needed to protect staff and customers because violent incidents continue to rise, despite the fact we've got tough on crime, and we've had a bit of a crackdown. The first two stores to switch on the facial recognition technology are in Te Rapa and Hamilton South, both in the Waikato, but a nationwide rollout is planned. The company says the technology will help identify serious repeat offenders, it will reduce theft, and they do this after what they say is a sharp increase in threatening behaviour.

Now this whole thing has taken forever for Bunnings. In Australia, Bunnings fought for four years to get permission to do this. There were courts involved, there were tribunals involved, there was a lot of controversy, and a four-year battle. Here, for Bunnings, it's only taken six months because Foodstuffs had already got approval from the Privacy Commissioner, so the hard work was done. But even so, six months for Bunnings to finally roll out a little bit of facial recognition in their stores. They worked hard at it, they've been taking privacy guidance. The Foodstuffs trial last year scanned 225 million faces and they deleted all the images within a minute, but there were concerns at the time about misidentification and bias and the need for strong safeguards, so Bunnings worked away at all of this. They hired a Māori digital sovereignty expert —who knew such a thing existed or was even needed— to make sure cultural considerations are built in. There is bilingual signage for the facial recognition, and if you think you've been wrongly identified as a bad guy, there are clear pathways for you to object to all of this.

But you know, all this kafuffle about getting the permission shows all of us that there are still a load of people in this world who do not like the idea. There's more issues to come, but are you worried about the rise and rise and rise of facial recognition technology? Or do you have no problem with it because it's a tool to fight crime?

Now all of this reminds me of debates I used to listen to on when Leighton Smith used to do this show. And he would do a show and it's all about freedom and liberty, and people would come on and say, “Oh, there's no problem, no problem at all, mate. If you've got nothing to hide, you've got nothing to fear." And Leighton would say, “Yes, but bit by bit, little by little, our personal freedom and liberty is being stripped and replaced by an all-powerful state monitoring our every step and then controlling the way we behave. It's the threat of Big Brother." But the difference now that time has passed, it's not actually the state that's doing all the facial recognition, it's the corporate world.

So it's not the state, it's the corporates, and the corporates seem to want to know every little thing about us. Your phone is monitoring where you are, what you do, what you look at, it's telling you what to think. And I get tired of being told what I should be listening to next by Spotify because they've looked at what I've listened to before and said, “well, this is you," and I go, “well, actually, I'm a broader, wider person than that, and stop bothering me." I'm tired of my car telling me how to drive, “your tyres are a little flat, would you like to check into the service centre?" No, I would not. I don't have the time right now. Would you shut up, car? I'm trying to drive.

Facial recognition technology, do you have any problem with it? And I know you do because look how long it's taken to get approval and how many people have had conniptions about it and had worries about it, and the Privacy Commissioner has spent millions on it just investigating this sort of thing. Is this the rise and rise of Big Brother, or is this necessary as we fight crime?
