The NZ tax year ends 31 March, not 30 June like in Australia.

I am considered a trader in NZ & therefore selling shares at a loss on 31 March & buying them back 1 April, has tax advantages...

Of course you want to "pay tax" as a trader, ie the only true indication of success IMO.

I have a nice "tax problem" due to profits ADY, whereas im still on a 40% odd loss on Uran.

There would be a few long term Uran holders in this boat id imagine?
