Weight, length/height and head circumference measurements are variously taken at Well Child checks. Growth charts for children aged 0–5 years can be found on pages 75–84 of the Well Child / Tamariki Ora Health Book or on the Ministry of Health website.

Achieving a healthy body weight and composition is of importance in preventing disease and promoting wellbeing. Health risks are associated with being both over and underweight. Efforts to achieve a healthy body weight should begin in childhood.
