What is Menopause?
Menopause is when your monthly periods stop for good. It happens because your body stops making as much oestrogen and progesterone, two important hormones.
You've reached menopause when you haven't had a period for 12 months in a row.
Menopause usually happens between ages 45 and 55. In Aotearoa New Zealand, the average age is 52.1
~7 in 10 women

~1 in 4 women
need support from a doctor, especially if the symptoms are strong or last a long time. 2
Stages of Menopause
Perimenopause
Hormone changes
Perimenopause is the transition phase leading up to menopause, when the ovaries begin producing fewer eggs and hormone levels (especially oestrogen) fluctuate. These changes can cause symptoms such as irregular periods, hot flushes, sleep disturbances, mood changes, and brain fog. Perimenopause often begins in the 40s, but it can start earlier, and symptoms may last several years before the final menstrual period.17
Menopause
Final Menstrual Period
Menopause is reached when a woman has gone 12 consecutive months without a menstrual period. This marks the end of natural fertility and occurs, on average, around age 51 in New Zealand. Hormone levels stabilise at lower levels, and some symptoms may continue during this time. Menopause is a single point in time and once reached, a woman transitions into postmenopause.18
Postmenopause
12 Months After Final Menstrual Period
Postmenopause begins one year after the final menstrual period and continues for the rest of a woman’s life. Some symptoms may ease as hormones stabilise, while others, such as vaginal dryness or sleep changes, may persist. Lower oestrogen levels during postmenopause can increase the risk of conditions such as osteoporosis and cardiovascular disease, making ongoing health monitoring important.19
