One economist says high inflation shouldn't be solely blamed on the Government.  

It's hit 5.9 percent today, the highest figure in 30 years.  

Kiwibank Chief Economist Jarrod Kerr says the Reserve Bank will probably lift interest rates to cool it down.  

He told Heather du Plessis-Allan there are domestic reasons but we can also blame international factors. 

“The global supply chain which has seized up, and caused a massive spike in shipping costs globally. The fact that petrol prices are up 30 percent.”
