The concerns I’ve stated about New Zealand’s comparative economic performance aren’t unusual. They’re shared by others, often in spades. In a recent edition of Idealog magazine, Vincent Heeringa writes:
In 1909 . . . New Zealand’s GDP per capita was at the head of the pack with the US, Australia and UK. By 2001 . . . we’d been leap-frogged by 16 countries and sat level with Taiwan. At present rates, we’ll be pegged with Kazakhstan in 2025.
Cue the Borat jokes. But how bad is the situation really? As I’ve said previously, I’m keen to get beyond the scary headline statistics, and understand what this all actually means for us in practical terms.
Policy Progress reader Achela has made the point a number of times in comments that our labour productivity — how much we produce per hour of work — is more important than our absolute level of production. So I’ve dug up the following stats from the OECD:

Source: OECD
New Zealand’s relatively low productivity rate echoes our low per capita GDP — in fact, our ranking (22nd out of 30) is identical.
It’s rather dispiriting but also, as I set out in a previous post, a bit puzzling. Are we really that inefficient at making things? And is that true across the board, or are we being dragged down by a few weak areas? Perhaps our economy is just focussed on less capital-intensive and therefore less productive industries?
Fortunately, while most papers on productivity tend to focus on national aggregates (and often leap to wild conclusions), a paper that Geoff Mason and Matthew Osborne of the UK National Institute of Economic and Social Research wrote for the New Zealand Treasury a few years back burrows down to sector level and starts to answer those questions.
The paper is entitled Productivity, Capital-Intensity and Labour Quality at Sector Level in New Zealand and the UK. It compares productivity levels in 21 different market sectors of the economy in 2002 and shows that beneath the unfavourable overall picture (NZ’s average labour productivity was only 77% of the UK’s) there is considerable sectoral variation.
According to Mason and Osborne’s analysis, there are five market sectors that stand out as having a productivity lead over the UK. These are (with their ANZSIC-1996 standard description):
- Cultural and recreational services (128% UK): units mainly engaged in providing cultural and recreational facilities and services. Sub-divisions: Motion Picture, Radio and Television Services; Libraries, Museums and the Arts; and Sport and Recreation.
- Communication services (115% UK): units mainly engaged in providing postal, courier and telecommunication services. Sub-divisions: Postal and Courier Services; and Telecommunication Services.
- Accommodation, restaurants and bars (113% UK): units mainly engaged in providing hospitality services in the form of accommodation, meals and drinks. Sub-divisions: Accommodation; Pubs, Taverns and Bars; Cafes and Restaurants; and Clubs (Hospitality).
- Finance and insurance (112% UK): units mainly engaged in the provision of finance, in investing money in predominantly financial assets, in providing services to lenders, borrowers and investors, in providing insurance cover of all types, and in providing services to insurance underwriters and to people or organizations seeking insurance. Sub-divisions: Finance; Insurance; and Services to Finance and Insurance.
- Food, beverage and tobacco manufacturing (105% UK): Sub-divisions: Meat and Meat Product Manufacturing; Dairy Product Manufacturing; Fruit and Vegetable Processing; Oil and Fat Manufacturing; Flour Mill and Cereal Food Manufacturing; Bakery Product Manufacturing; Other Food Manufacturing; Beverage and Malt Manufacturing; and Tobacco Product Manufacturing.
In addition, Metal product manufacturing (probably dominated by Comalco) is just ahead of the the UK, with 102%. Between them, these sectors account for 30% of the New Zealand economy.
Also, the figures for the crucial sectors of Agriculture, Forestry and Fishing (which account for 10% of the economy) are considered problematic and may be higher than the 78% estimated.
Plus, there are two sectors — mining and business services — where New Zealand is behind the UK on labour productivity but ahead on multi-factor productivity. The report says, “This suggests that, although New Zealand firms in these two sectors are on average less capital-intensive than their UK counterparts, many of them make more efficient use of existing resources.”
New Zealand economist Brian Easton has cast a careful eye over this paper in Some Notes on New Zealand Economic Growth Research, and adds that, at the other end of the scale:
it would appear that 73 percent of [New Zealand's] productivity deficit can be explained by the weaker performance of the manufacturing sector, 38 percent by the total distribution sector, and 27 percent by the construction sector. (They sum to more than 100 percent because there are some New Zealand sectors which are productivity stronger than their British equivalent.)
Mason and Osborne also address the question of whether New Zealand’s low rate of productivity is because we are focussed in sectors that (both here and the UK) have relatively low rates of productivity compared to other sectors. They calculate that roughly a quarter of the labour productivity gap relates to this.
Easton also notes that “there is a sense that while there are variations in the productivities between sectors, the Brits are better at deploying their resources in sectors where they are highly productive, rather than in sectors where their relative productivity is lower. At the very least this exercise shows sectoral composition matters.”
He contrasts the work undertaken by Mason and Osborne with other reports on this topic:
Too much of New Zealand’s research is about aggregate productivity, and draws policy conclusions based on that indicator with little – if any – attention to the sectoral differences. It seems likely that unless they address these issues, any conclusions drawn from the research must be at best limited and inefficient, if not darned wrong.
I agree. There are possible pointers in Mason and Osborne’s report for where further, sector-specific research could be undertaken. But is also valuable to understand that New Zealand’s labour productivity is not uniformly lower than that of other countries like the UK. Rather, there is a mix of some sectors where we are more productive and others (a larger number) where we are less productive. This suggests that we do not have a single unitary ‘productivity problem’, and therefore there is not likely to be a unitary solution, either.
That will be a useful insight to hang onto as we continue with the Progressive Path to Prosperity work programme.








It’s great to see the debate on redistribution vs. altering market power and outcomes
