Yes and you get a kind of reverse problem moving a UK pension to NZ. UK pension savings are not taxed at all, so you have more money earning for you throughout your working life. The money is taxed (a certain amount may be removed tax free first) as income once you start taking your pension.
However move the capital from the pension fund in the UK to NZ and NZ will stick you with a massive tax bill...for money you already own and which you did not earn in NZ..!
If you move it in the first 4 years its all tax free, if you don't move it in the first 4 years I would leave it there, and as you withdraw it NZ would treat it as taxable income and the UK NZ Tax treaty *SHOULD* mean the UK doesn't tax it and its only Taxable by the IRD
