The commerce committee of the new Parliament is chaired by Todd McClay and has until February 29 to decide whether to readopt the inquiry.
"The committee has not had the opportunity to consider the work programme as yet," McClay said.
"We need to consider the advisability of pushing ahead with the inquiry at the time when the consultation and legislation is pending."
Minister for Primary Industries David Carter last month said consultation had opened on the Government's proposed response to reviews of how dairy company Fonterra set its farm-gate milk price - that which is paid to farmers - and the Raw Milk Regulations.
Work by the Ministry of Agriculture and Forestry, with input from economic, regulatory and legal experts, had resulted in a set of preferred options for amendments to the Dairy Industry Restructuring Act and the Raw Milk Regulations, Carter said.
The Commerce Commission was recommended to monitor how Fonterra set its farm-gate price - a proposal which triggered speculation that dairy product retail prices could fall.
However, Carter said the review found Fonterra's approach was consistent with what was expected in a competitive market, although there was an issue with a lack of transparency.
Suggestions also included embedding the farm-gate milk price governance arrangements in legislation and requiring Fonterra to publicly disclose information about how it set the price.
Recommendations on Raw Milk Regulations included an increase in the total quantity of milk available to independent processors to about 5 per cent of Fonterra's milk supply, as allowed for in the act, and a three-season limit for those who sourced raw milk directly from farmers.
Government consultation on the preferred options would be in the form of a draft set of regulations and a draft bill, which would include changes to enable Fonterra's proposed capital structure change to have its farmer owners trade shares among themselves rather than with the company.
Submissions close on February 24.
Parliament had planned to consider:
* Various pricing points for milk from farms to shops and report on any practices that might have the effect of inflating the price.
* Impact and influence the practices of retailers and wholesalers have on the price.
* Impact of international market prices for milk on each of the pricing points.
* Whether the current regulations are adequate
