Donated wealth at the centre dealing with birth (5)

I believe the answer is:

natal

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

'birth' is the definition.
(I've seen this before)

'donated wealth at the centre dealing' is the wordplay.
'donated wealth' becomes 'nata' (I can't justify this - if you can you should believe this answer much more).
'at the centre' says to take the centre.
The middle letter of 'dealing' is 'l'.
'nata'+'l'='NATAL'

'with' acts as a link.

Can you help me to learn more?

(Other definitions for natal that I've seen before include "KwaZulu-____ , South African province" , "Of birth; former African republic" , "somewhere in Africa" , "former SA province" , "description of delivery" .)

I've seen this clue in The Irish Times.
