You'll never earn as much as you do in your 40s, data provided to the Herald by Statistics New Zealand reveals.
Those aged between 40 and 44 earn the most throughout their career, recorded at $1325 gross earnings before tax per week, but that average dips - by a few dollars - for those slightly older, aged between 45 and 49, at $1323 per week.
The data shows those in the 15 to 19 age bracket unsurprisingly earn the lowest income and those aged 40 to 49 earn the highest.
Alan Pettersen, director of HR consultancy Positive People, said the 40s age bracket is when most people are at the peak in their careers.
"Whether having had a long training period in tertiary institutions as a younger person or having learned the ropes on the job since leaving school, the 40s is the time when most working people are fit, well, energetic and highly motivated to meet family and domestic commitments," he said.
