Charger for New Zealand

Hi, I’m looking for a New Zealand charger for my homebase and robovac 11s.
Any advice or help where to found one?

I believe the AC adapter for the homebase works for 100V-240V. You just need a plug adapter to accept the US two prong and adapt to the NZ plug type. These cost a few dollars only. Sample image: https://www.amazon.com/Plug-Adapter-Australia-Zealand-China/dp/B00U0YX6X4
