Pepa parahi

Whakaahuatanga poto:

Pepa parahi e pa ana ki te parahi hiko, ko nga huanga konutai hei taonga, ma te tukatuka i te wera, ma te maimoatanga wera, te horoi, ka mutu, ka oti, ka mutu, ka oti te horoi. Nga mahi a te rauemi e mahia ana, he kirihou, he taonga miihini, te aukati i te aukati, te mahi me te tine pai.
