KEY POINTS:
Latest estimates put New Zealand's population at 4.25 million.
Figures released today by Statistics New Zealand showed the resident population increased by 40,600 (1 per cent) in the year ended December 2007, to an estimated 4,252,000.
Population growth last calendar year was mainly due to there being more births than deaths, as opposed to immigration.
At December 31, the median age for women was 37 and 35.4 for men, Government statistician Geoff Bascand said.
