The mural crown (a crown depicted as if made of stonewalling) is common as a crest in city coats of arms. It is coloured silver, and from its top comes a swimming dolphin. Around the crest is mantling in red. The supporters on either side of the shield are a golden heraldic lion with a chained collar around its neck to the left, and a moa in its natural colouring on the right (the terms "sinister" and "dexter" relate to the shield from the holder's point of view, not the viewer's, thus dexter is the viewer's left and sinister is the viewer's right). The base on which the supporters stand is normally not emblazoned but is left to the artist to decide. The Motto may be translated as "Supreme by position".
