The Royal New Zealand Navy, the New Zealand Army and the Royal New Zealand Air Force all have special flags. The flags flying in this photo are the versions used when Queen Elizabeth or her New Zealand representative – the governor-general – is present. They were flown at the swearing-in of Governor-General Sir Jerry Mateparae on 31 August 2011. These flags are called the Queen's Colours and are embellished with a crown or the Queen's initials ('ER', which stands for Elizabeth Regina) and other decorative elements. The Queen's Colour of the Royal New Zealand Navy is at left, the Queen's Colour of the 1st Battalion Royal New Zealand Infantry Regiment is in the middle and the Queen's Colour  of the Royal New Zealand Air Force is at right. The more commonly flown military flags do not have the Queen's symbols on them. The Navy unveiled a new Queen's Colour on 1 October 2011.
