Mr Amiatu will also lead the translations of the Roman Missal and the sacramental books from English to Samoan.
He said he was both “shocked and happy”, when the archbishop approached him (Mr Amiatu) with the proposal.
“There was no dialogue in the lead up to this,” Mr Amiatu recalled.
“Once the greeting was done, he (Archbishop Mataeliga) said, ‘right’ and launched straight into it. I was shocked and happy that he thought of someone like me to go across and undertake such an appointment.”
