Ko toku hoa ko Hemi, it is my friend Hemi.
He kai ma tona tupuna ma Paora, food for his grandfather Paora.
In these examples, "toku hoa", and "tona tupuna", are more general terms than "Hemi" and "Paora", and they therefore stand first; and "ko" and "ma" are repeated with the particular names "Hemi" and "Paora".
