Paying Taxes in Malaysia

I have sent some money over to Malaysia to open an account as aparently I had to do that. The account has been opened and the money i sent over to open the account is in the account however when I try to transfer my money back (not all of it) they say I owe taxes on it. Is this correct as the money I earned here in NZ and only sent it over as they insisted I needed to, to open the account but I don't understand why I have to pay taxes on it. the other thing is they are saying that i have to pay them the money from here in nz but it can't come out of my account that has been set up over there is this correct and if so how do I get around this as it is the only lot of money I have and it is going to take me a while to save up to pay the taxes that they are asking for. I look forward to your speedy reply.
