1. What is Pregnancy Weight Calculator NZ?

The Pregnancy Weight Calculator NZ provides evidence-based recommendations for healthy weight gain during pregnancy according to New Zealand Ministry of Health guidelines. It helps expectant mothers maintain optimal health for themselves and their babies.

2. How Does the Calculator Work?

The calculator uses BMI-based weight gain recommendations:

Recommended Gain (kg) by BMI Category:

  • Underweight (BMI < 18.5): 12.5 to 18 kg
  • Normal Weight (BMI 18.5-24.9): 11.5 to 16 kg
  • Overweight (BMI 25-29.9): 7 to 11.5 kg

Explanation: These guidelines are based on pre-pregnancy BMI and are designed to support healthy fetal development while minimizing pregnancy complications.
