This is a video of the Kapa o pango witk lyrics and you can read the traduction delow :

Let me become one with my land
         This is our land that rumbles
         We are the All Blacks
         It is time! This is my moment!
         Our Reign
         Our supremacy will triumph
         And we will reach the top!
         The silver fern!
         All Blacks!
         The silver fern!
         All Blacks!
