Cadbury's new-look marshmallow Easter eggs for 2019 are being called Easter "humps" and "rocks" online.

But no-one's laughing.

Kiwis are outraged that the Australian chocolate manufacturer is selling easter eggs that are shaped like one half of an egg.

It replaces the old egg-shaped style where two halves were joined together, creating a crunchy chocolate layer in the middle.

"Cadbury needs to leave things as they are. They are eggs not just a hump," wrote one commenter.

Another said: "I loved pulling apart the marshmallow eggs!! What is wrong with you Cadbury?! Talk about giving the middle finger to all of the NZ market. That's the last straw for me."

Cadbury Cadbury's odd new egg this Easter is infuriating shoppers.

Many commenters said one of the best things about the old marshmallow eggs was the double layer of chocolate where the two halves joined together.

"What next!!! Oh bummer. Love pulling them apart. Plus that extra choc gave it a bit of crunch. Gosh I wish Cadbury would stop changing things that are perfectly fine," posted an angry woman.

Cadbury posted that its new equipment in Australia couldn't replicate the old shape.

But on the up side it said: "Our marshmallow eggs will now use sealed flow-wrap packaging, meaning marshmallow eggs will stay fresh for longer."

And it also told social media followers that Kiwis would be getting "just as much marshmallow egg for their buck".

"In fact, one of the share packs - the 175g pack - is now cheaper per gram than it was last year," Cadbury said.

It said people tested on the half eggs reported "a very similar eating experience to the old shape".

EWAN SARGENT/STUFF Last year's New Zealand-made Cadbury Easter eggs featured an egg-shaped egg. The Aussie equipment can't manage to do that.

The previous egg-shaped eggs were made in the Dunedin factory that Mondelez, Cadbury's owner, closed last year.

Now all Cadbury chocolates come from Australia to New Zealand.

Many posts pointed out the half-egg controversy doubles down on anger still felt over changes to Roses chocolates.

In September last year, Cadbury added two new flavours, white raspberry and vanilla nougat, and re-jigged the recipes of its classics, hazelnut creme crisp, turkish delight, hazelnut swirl, caramel deluxe, classic caramel, dark mocha nougat and classic milk.

One commenter said: "Why change things that are not broken? I love pulling apart the two halves and enjoying the thick chocolate. Well I guess I won't be buying your eggs anymore. You cocked up your Roses and now you are cocking up yet another classic."
