Super-sized eggs of all colours are to be placed around the country - making for the ultimate Easter egg hunt.
The Whittaker's Big Egg Hunt will start next month in a bid to raise funds for youngsters being treated at Auckland's Starship children's hospital.
Photos and details of the eggs are not being made public until they are placed throughout city centres - in Auckland, Wellington and Christchurch - on March 12.
There are prizes for people who find the eggs, which will be hidden around the cities.
At the launch at Vector Arena last night, all 100 super-sized eggs were put on tall stands spaced out on the stadium floor.
