The income tax calculate amount fill in AS100 is using deduct NI or not?

I working remotely in UK for the same HK employer and same employment contract. The HK employer has no presence in the UK and my salary will be paid to my HK bank account. As per request, I already create the PAYE Employer's account to pay my NI for my monthly overseas income. My question is:- 1) I pay the NI by myself, can I claim the amount in SA100 / Tax reliefs # 3? 2) I still need to pay the provident fund in Hong Kong, can I also claim the amount in SA100 / Tax reliefs # 4? Looking forward for your reply! Thanks! Wen
