Moving from the Middle East to South Africa

I am a British citizen who has worked in the Middle East for 10 years. During this time I gained South African citizenship and will move to live in SA. Will I need to pay tax on the money I earned in the Middle East during the financial year in which I move?

Any information that you can provide would be appreciated.

No you will not, even as a South Africa citizen you were outside South Africa for long enough and earned your income outside SA so it cannot be taxed here.
