Mixed signals from 22 years of competition data
The Commerce Commission has released its first State of Competition report, using 22 years of Stats NZ firm‑level data to give brokers a data‑rich view of how rivalry between New Zealand firms has shifted since 2001. The study builds baseline indicators across concentration, business dynamism, and market performance for future monitoring.
Chair John Small (pictured) says the high‑level message is nuanced: “The report finds that while business concentration has reduced on average, competitive pressure has weakened in many parts of the economy.”
Rather than a simple story of more or less competition, the data show market power easing in some places while the churn of firms slows. Industry concentration has edged lower, particularly since the global financial crisis, suggesting more players or more even market shares.
At the same time, churn in the business population has slowed markedly, with entry and exit rates falling and fresh entrants capturing a smaller share of industry revenue than in the early 2000s. Rank‑persistence measures show large incumbents increasingly holding their ground.
As Small notes, “This suggests that market conditions are favouring larger incumbent businesses and, while smaller, newer businesses may be able to enter markets, it is harder for them to displace the established players.”
Upstream sectors shape costs for households and lenders
For advisers, the most relevant findings sit in upstream sectors that shape mortgage pricing and operating costs, especially electricity, gas, water and waste services, and financial and insurance services, which were assessed as having relatively weak competition and high ‘upstreamness’ in supply chains.
According to Small, “These upstream industries are critical for our economy. Weak competition in these markets can mean higher costs and lower-quality services cascade through to businesses and households.”
Persistent input‑cost pressure in energy and finance can ultimately influence banks’ funding costs, mortgage rates, and the affordability of new housing supply.
The report also highlights lower competitive intensity in parts of the broader services economy, while sectors such as construction, accommodation and food, and administrative and support services appear more competitive and improving.
Implications for brokers, first‑home buyers, and investors
For mortgage and finance brokers, the findings underline why headline cash‑rate moves do not always translate cleanly into sharper mortgage rates or better lending terms. Where incumbent lenders or insurers face limited challenge, pass‑through of efficiency gains can be weaker and innovation slower, affecting borrowing capacity for first‑home buyers and property investors alike.
At the same time, the commission’s work signals continuing regulatory attention on banking, payments, and infrastructure – areas that could, over time, foster more diverse funding models, new digital lending platforms, and sharper pricing for credit‑worthy borrowers.
Advisers who closely track these shifts will be better placed to explain the structural forces behind rate movements and to source competitive options in an environment where, as the report stresses, “competitive markets are critical to New Zealand’s economic performance.”
