Off-grid living for an european

Hello Guys,

I am a 15 year old Boy from Germany who would Like to know If it would be possible for an european Like me to one day be able to live off-grid in new Zealand. I've looked a Bit into this topic and Just found that you'd either have to Invest into new Zealand, have some Family members there or be Like over 55 years old. So is my only way to fulfill my life Goal of living "free" (Off-grid) in new Zealand to become rich and Invest a Minimum of 1.5 Million NZ$ while also still have g at least 1 Million NZ$ in Reserve? Ist there Maybe another way? Maybe someone would adopt me? Would that bei possible? In the end I Just want to live a simple live while living in coexistens with Nature.

Hope I'll get an answer soon. 😄
