Research found children in the UK received on average eight chocolate eggs each at Easter - about 12,000 calories and around 270 teaspoons of sugar, the Daily Mail reported.
Healthy Food Guide nutritionist Claire Turnbull believed Kiwi kids consumed less Easter chocolate than their British counterparts. However, even three large Easter eggs in one day "is a massive amount of sugar and saturated fat in one go, and a lot of calories", she warned.
And while an Easter chocolate gorge was unlikely to have long-term health effects, it would not be "particularly helpful" for children, she said.
To help prevent kids over-indulging on chocolate, she recommended running an Easter egg hunt with a group chocolate egg prize to reduce the amount each child consumed.
And beginning the Easter weekend with a boiled egg breakfast accompanied by "toast soldiers" would help children associate Easter with real eggs. Mrs Turnbull also recommended encouraging youngsters to spread out consumption of Easter treats, if possible over a few weeks.
