Well, she hasn't recited it. There is a difference between an EV (Ardern's claim) and a mild hybrid (Toyota's planned Hilux). The Hilux wont be eligible for a subsidy, and will retain its original ORC, providing it comes to market.
She has at best, stretched the truth regarding Toyotas press release in an attempt to smooth the pushback from the public over this tax grab/subsidy. If not she has misrepresented info from Toyota in which case someone in that position shouldn't be spreading 'misinformation' and further confusing the public (transparency and all that).
The fact that Toyota CEO publicly refuted her claim should be enough to put to rest, but it seems her faithfuls are always there to go into bat for her.
But lets be honest, she has quite the record of lying so on the back of no new taxes (apart from the 39% top tax rate) promise in the 2020 election campaign, whats another lie or broken promise to add to the telly.
