What was your purpose when you invested. To ride the hype and earn a nice 'capital gain'?
Given the short time frame, on the face of it it would be taxable. The tax rate is your marginal tax rate so probably 10.5% since I dont think you pay ACC on share profits. http://www.ird.govt.nz/how-to/taxrat...etaxrates.html
I am not sure if you would have complete a IR3 or if there is a short cut method to advising IRD.
