Renewal Cameroonian Passport (Yaoundé)

Hi all,

my partner is from Cameroon but living in New Zealand. His passport is about to expire thus he needs to renew it.

We can't for the life of us find any information anywhere or from anyone on how to do this from where he is. We have tried calling different embassies around the world.

Can anyone offer any help in this regard PLEASE?

Thank you very much,
Samara.
