According to Grant Robertson today:
"New Zealand’s growth per person is significantly lower than countries like the UK and America, showing our economy is driven by population growth rather than productivity, says Labour’s Finance spokesperson Grant Robertson.
“Along with flat per person growth, we have seen a fall in per capita real incomes. This means on average Kiwis are getting poorer. That’s because the key driver is population growth, not new businesses, industries and exports which is what’s needed to boost growth per person."
I queried the OECD database for GDP per capita between 2008 and 2015:

This shows that the growth in the UK was 2.4%; in the US, 4.4% and in NZ, 7.5 %
Here's the data graphed.
No NZ isn't flash overall but it's comparatively better now than it was when Labour left office.
Robertson even included Japan in his headline yet their growth was lower than the UK or US between 2008 and 2014.
