He told NZPA the Government would not provide subsidies to New Zealand consumers, and high international prices would benefit the economy.
New Zealand exports at least 95% of everything that it produces. The higher pricing for the country’s commodities -- milk, meat, wool, vegetables etc -- means more money flows into the New Zealand economy, which means more money being available for domestic consumers, Carter was quoted saying.
On Thursday, Mr Carter asked officials for a report to look at whether the market was competitive and whether one operator wasn't "gaming New Zealand consumers".
Green Party food spokeswoman Sue Kedgley has called on the Government to set up a full Commerce Commission inquiry into dairy pricing.
Consumer New Zealand has also called for a full investigation.
The country, Kedgley said, need much greater transparency into the pricing practices of the grocery retail sector, especially in areas like dairy where there is very little real competition.
Kedgley said the inquiry should investigate claims by farmers that they receive less than 30% of the price of milk and why high international dairy prices are to blame for rising prices.
Fonterra on Friday announced it would freeze domestic milk prices until the end of the year after widespread criticism that milk had become unaffordable for many families.
However, the dairy co-operative's decision has baffled some in the dairy industry, who say it is unnecessary and could "end in tears".
Countdown, Woolworths and Foodtown supermarkets pledged to freeze their milk price for the rest of the year.
Foodstuffs -- which covers Pak'nSave, New World and Four Square stores nationwide -- yesterday said it would freeze its prices as long as suppliers did.
