Advice on using a VPN to stream

I’m looking for some help , I’m trying to watch a show from the streaming site tvnz and I Have my VPN set to new Zealand but it still won’t play.
A box pops up over the video and says “error code: VID-GEO”. Is there a way I can stream without trying another VPN I’ll need to pay for?

Look for a VPN that can get you a dedicated IP in NZ
