"Why can we see Aurora in NZ, we aren't Iceland & why do our Aurora look different to Aurora Borealis". Simply we are relatively closer to Geomagnetic South Pole & more often than not we are looking side on at it from NZ. I made this years ago as a basic guide

Also FYI here's the world's easiest explanation of what an Aurora is. The sun 'burps', the wind is magnetically charged particles, the wind hits us & is drawn back into the poles. Thank GOD for our iron core & magnetosphere or we'd be like Mars without an atmosphere. youtu.be/HJfy8acFaOg?...
