On the right side, is the flag of the New Zealand Shipping Company. A white (indicated by no shading) rectangular flag with a red (indicated by vertical shading) cross overall and raised initials ‘ N Z S Co.’ in the quarters. On the left side, is the flag of the Federal Steam Navigation Company. A white (indicated by no shading) rectangular flag with a red (indicated by vertical shading) cross overall and a blue (indicated by horizontal shading) rectangle in the centre placed over the cross.
