But Associate Professor Rachael Taylor, a children's nutrition researcher at Otago University, said making children eat when they aren't hungry is a bad habit that could be contributing to New Zealand's obesity problem.
We have the third highest rates of obesity in the developed world for both adults, 31 per cent, and children, 11 per cent.
"We know that children when born have a good ability to regulate their appetite. They have lost that by the age of 3 or 4," said Taylor.
Parents should encourage children to be guided by their own hunger cues. Not listening when the body signals it doesn't need food is "setting them up for a lifetime of eating when they don't need it".
The survey found kids love fruit, but vegetables topped the list of most-disliked foods.
The Health Ministry's latest nutrition survey found 75 per cent of children ate the recommended 2+ servings of fruit a day and 57 per cent ate the recommended amount of vegetables, 2+ a day for 2-4-year-olds and 3+ for older children.
The Swisse survey, done by Bauer Media Research and Insights, found 53 per cent of parents give their children vitamin supplements. Multi-vitamins were the most common type, followed by vitamin C.
Auckland University child health expert Associate Professor Cameron Grant said it was reasonable for children to be given vitamin and mineral supplements because there was relatively little fortification of New Zealand foods with the likes of vitamin D and iron, compared with many other developed countries.
Iron deficiency in young children, and vitamin D deficiency rickets were more common in New Zealand than in countries with more vitamin and mineral fortification.
Multivitamins would be better than vitamin C, Grant said, and the first two years of life was the time of greatest need.
