Tax on foreign income

I am currently living in New Zealand under a 5 year visa, however receive rental income from a property in the UK. I was wondering : 1) Do I need to declare the New Zealand based income (which I will be taxed in New Zealand for) on my UK tax return 2) If the New Zealand income will affect the rate at which I pay tax on my rental income in the UK (i.e. will it push me into a higher tax bracket)

Hi,
1. No it is only UK income that you need to declare  
2. No
Thank you.
