I moved of to australia part way through the tax year and then returned to new zealand and worked. when i filed my tax return it was automatically complete in new zealand due tothe IR3 file, but a tax return in Australia was done. My new zealand one was completed before hand with my australia one to follow. my australia one states that i owe an amount of tax due to not being a tax resident for tax purpose so i occured interest, and my nz tax was based off my whole income earnt including international. but that came back saying i owed tax as well. Can someone explain how this may have occured, or how i can possibly resolve this? thank you
