Competition in New Zealand's economy isn't as strong as it could be. 

New Commerce Commission analysis of 22 years of Stats NZ data shows average business concentration has dipped slightly. 

However, smaller businesses are still struggling to gain traction against larger firms. 

Commission Chair John Small says weak competition in essential sectors is also weakening the rest of economy.  

He told Mike Hosking that while the size of New Zealand does have an impact on the amount of competition we have capacity for, we can still do a lot better than we are.
