Three-quarters of New Zealand children were aware of the sacrifices their mothers made - more than 10 per cent lower than the average of the 12 countries included in a new survey.
And this Mother's Day, nearly a third of Kiwi mothers would be happy with a simple "thank you".
The Attitude to Gratitude survey, commissioned by Procter & Gamble (P&G), investigated attitudes to Mother's Day - which is this Sunday - and parenting by 3000 respondents across 12 countries.
Of the 15- to 55-year-olds with mothers still living who answered the survey conducted by independent research agency Ipsos, 250 were from New Zealand.
The other countries were Australia, China, India, Indonesia, Japan, Malaysia, Philippines, South Korea, Thailand, Singapore and Vietnam.
