<P> While filled eggs were first manufactured by the Cadbury Brothers in 1923, the Creme Egg in its current form was introduced in 1963 . Initially sold as Fry's Creme Eggs (incorporating the Fry's brand), they were renamed "Cadbury's Creme Eggs" in 1971 . </P> <P> Creme eggs are usually sold individually but are also available in boxes containing a varying quantity of eggs depending on the country the packaging is intended for . The foil wrapping of the eggs was traditionally green, red, yellow and blue in colour in the United Kingdom and Ireland, though green was removed and purple replaced blue early in the 21st century . In the United States, some green is incorporated into the design, which previously featured the product's mascot--the Creme Egg Chick . As of 2015, the packaging in Canada has turned into a 34g, purple, red and yellow soft plastic shell . </P> <P> Creme eggs are available annually between 1 January and Easter Day . In the UK in the 1980s, Cadbury made Creme Eggs available year - round but sales dropped and they returned to seasonal availability . </P> <P> Creme Eggs were manufactured in New Zealand at the Cadbury factory in Dunedin from 1983 to 2009 . Cadbury in New Zealand and Australia went through a restructuring process which most Cadbury products previously produced in New Zealand being manufactured instead at Cadbury factories in Australia . The Dunedin plant later received a $69 million upgrade to specialise in boxed products such as Cadbury Roses, and Creme Eggs were no longer produced there . The result of the changes meant that Creme Eggs were instead imported from the United Kingdom . The change has also seen the range of Creme Eggs available for sale decreased . The size also dropped from 40g to 39g in this time . The response from New Zealanders has not been positive . Complaints have included the filling not being as runny as the New Zealand version . </P>
