Kiwis took offence to the prices of supermarket staples primarily, products like butter, milk, eggs, flour, fresh produce, meats and bread.
The number of complaints has been levelling out recently, with fewer than 10 complaints lodged for the second week in a row.
An MBIE spokesperson said the types of complaints remained consistent, "with the cost of face masks, petrol and milk being some of the most complained about items".
In the 40-odd days since then, the rise in the number of complaints has been slight. Between June 4 and June 10, just seven complaints were made to Price Watch.
A spokesperson for the Commerce Commission said it was up to them to assess the complaints and decide whether or not to launch investigations.
"The vast majority of the complaints referred by MBIE were about issues that had already been raised directly with the commission," they said.
"The complaints referred by MBIE covered a wide range of issues including price increases, surcharges, travel and event cancellations and non-performance of contracts.
