I want to find out if the Irish hymn "A Mhuire Mháthair" uses the tune of the New Zealand Maori song Pokarekare Ana.

I run a website of historical New Zealand songs.

The most popular songpage on it, with worldwide visitors, is Pokarekare Ana, a Maori love song dating from World War One, and nowdays almost a second NZ national anthem.

This webpage has the song's lyrics, tune variants and history.
NZ Folksong - Pokarekare Ana

I have received an e-mail from Ireland reporting that the tune of Pokarekare Ana is used in "A Mhuire Mháthair," a hymn sung at Irish weddings.

1. Can anyone confirm this?
2. If so, is it in 3/4 or 4/4 time or in another timing?
3. Can anyone e-mail me an MP3 or score or ABC notation of the exact tune used for A Mhuire Mháthair?
4. Is there any history of A Mhuire Mháthair being sung to the Pokarekare Ana tune before WW1?
5. If not, when was it composed?
6. Is the Pokarekare Ana tune used for any other Celtic songs?

A Mhuire Mháthair,
Sé seo mo ghuí,
Go maire Íosa,
Go deo i'm chroí.

Ave Maria
Mo Ghrá Ave,
Is tusa mo Mháthair,
Is Máthair Dé.

Thanks
