"We regularly review the flavours available in a box of Roses to ensure we reflect the changing taste preferences of our consumers," said James Kane, country head of Mondelez New Zealand.
"When we add new pieces we need to make way by removing something, and with Cherry Ripe still available in the full size bar and large box of Cadbury Favourites, we're confident fans will still be able to enjoy the signature cherry and coconut hit.
"We promoted the new Dark Mocha and Salted Caramel pieces back in May and these are flavours that we know reflect the current taste preferences of consumers."
Cherry Ripe caused a stir last year when a woman complained on social media of a disproportionate number of the Australian chocolates in her son's Favourites Easter Egg.
Shelley Down, from Paraparaumu, posted an image of the offending package and questioned the company on their chocolate selection process.
"Was super excited to watch my son open his Favourites Easter Egg but had a bit of a WTF moment when we realised there were 7 Cherry Ripes and 1 Dairy Milk [sic]," she said.

"I know Cherry Ripes get a bit of a tough time and you still need to force them upon us but the ratio seems a bit drastic. Did you have a newbie working on the distribution line that day because surely this ain't right?!"
The post attracted over 3700 reactions and 412 comments - including from a number of other people with the same issue, which one person referred to as the "curse of the Cherry Ripe".
In response to her post on their Facebook page, Cadbury said the high number of Cherry Ripes in the Favourites Easter Egg was unintentional.
"Thanks for your feedback. Whilst the process of the pieces going into the packet is randomised, it is not intentional that you would get that much of one particular product."
A spokeswoman for Cadbury told the Herald: "While variation in the numbers of Cadbury mini bars in each pack is possible due to the random selection process, it is very unusual to have a majority of one bar.
"We encourage any customers who have a concern to contact us directly and we will investigate the matter further."
