During World War II, members of the Maori Battalion wrote their battlefield orders in Te Reo Maori to make it harder to decrypt their messages.

Decrypt the following whakatauki encrypted proverb using a Caesar cipher.

PKEWHNG PKNNG PKEWHNG UWHK PKEWHNG RUNU PKEWHNG PKAM

You have the following information:

1. The Maori alphabet is: a, e, h, i, k, m, n, ng, o, p, r, t, u, w, and wh. For the purposes of this exercise, you can ignore macrons.
2. You have a crib, this is a plaintext and ciphertext pair. The crib is the plaintext word TE and its corresponding ciphertext AM. You can assume that the same shift was used for the crib and the whakatauki.
