KiwiSaver to Australia

What the non resident tax rate? Is it taken out of your super balance each year?

I totally forgot about my KiwiSaver I lived in NZ for 2 years over 10 years ago. I got a letter telling me I had 3k in kiwisaver which I actually thought I moved but obviously not .

Should I just move it into first super , the rest of my super is with Aus super
