I mean all they need to do is copy & paste the Australian voice and then change "sex" to "sux" (as in the number 6), and "meelk" to "mulk" for milk. I could probably do it in 30 minutes if they give me the keys.
Ha ha. I think you’re more likely to get your hands on the keys to Willy Wonka’s Chocolate Factory than any sort of key from Apple.
 
Hey all

I think, this may relate to the Siri Responses language/accent. Whislt the iPhone Language & Region needs to be set to US as well as Siri Request Language, you can have Siri's responses in your local accent(s).

Edit:

Someone in another forum has stated this cannot b it as there has never ben a Siri NZ Local Accent setting so they may have gotten ahead of themselves a bit with that sentence then as cannot think what else it relates to as trying to set Region, iPhone Language, or Siri Language to anything other tan US deactivates AI Siri.
This does seem to be it. I’ve now been able to set my Siri voice to British, instead of being stuck with one of the American voices
