Place of labour? (5)

I believe the answer is:

natal

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for natal that I've seen before include "Province of South Africa" , "Pertaining to birth" , "former SA province" , "Relating to the time of one's birth" , "Of or from one's birth - in S African province" .)

I've seen this clue in The Mirror.
