I know these are not the exact lyrics she sings in the song, but they are a part.

Paho nei taku reo mou
Tatangi ake nei ki nga maunga teitei
Huri ana te mata o te whenua
Amio ana ki nga moana
Paho nei taku reo mou

Mate ana au i te aroha
Karu whiwhita, he kamo momohe
Whakamanawa ana ki taku kiri
E taku tau, e taku ngakau pumau
Mate ana au i te aroha

E taku tau, taku manawa e
Te tau o taku ate


Translation:

My voice reaches out to you
Resounding over the highest mountains
weaving through the contours of the land,
floating across oceans

I am lovesick
you with gentle eyes, soft lashes
warm to the touch
My love, my true love

You are the love of my life
my love, my heart
