Goldman Sachs has identified women as a "hidden labour pool" that could boost economic output by 10 per cent and solve an expected labour shortage as Christchurch is rebuilt.
The report, Closing the Gender Gap - Plenty of Potential Economic Upside, argues that New Zealand is only three-quarters of the way to unlocking the hidden value of its female workforce.
"Our estimates show that closing the gap in male and female employment rates in New Zealand would boost the level of gross domestic product by 10 per cent," said Goldman economist Philip Borkin.
The rebuilding of Christchurch would stretch available resources and labour shortages were likely, Borkin said.
A major construction company told Goldman Sachs that the pool of 77,000 tradespeople nationwide needed to more than double to rebuild Christchurch. A labour shortage could increase inflation and force the Reserve Bank to raise interest rates.
