You'll know soon enough, if you fly into Christchurch Aiport.
Night-time visitors will see the terminal alternately displaying pink and blue lighting – until we get word of the birth of the Duke and Duchess of Cambridge's baby.
The ability of the airport terminal to change colour is very popular with visitors. Christchurch Airport CEO Jim Boult: "Most nights, the lighting rotates through the colours of the rainbow, and often visitors wait to take a photo of the terminal in their favourite colour."
The airport can celebrate all sorts of significant events in this way – including red for Chinese New Year, pink to support Breast Cancer Awareness or blue for Men's Health Awareness. It's even gone red-and-black to support the Crusaders, and black-and-white for the All Blacks.
Boult: "Millions all over the world are waiting to see whether the royal baby is a prince or princess, so we're very happy to work with Monarchy NZ to be lit up when the future king or queen is born."
Prince William (the Duke of Cambridge) is very much in the hearts of Cantabrians. The Prince visited Christchurch on behalf of the Queen in 2011 to attend the National Memorial Service, following the devastating earthquakes that hit Canterbury.
The lighting colour scheme will herald the baby's arrival to thousands of people...because every day the equivalent of the entire population of Timaru passes through the airport.
