The Government has also invited the private sector to submit alternative proposals for a ferry service that will be assessed alongside the procurement process in March.
Peters said the Government is now opening the process for eligible parties to put forward their ideas.
“We announced in December that any better ideas than direct procurement of new ferries and port agreements for the enabling infrastructure will be heard.
“Interested parties should put their best foot forward now.”
Peters said alternative options must deliver the ferries by 2029 with appropriate freight and passenger capacity, provide confidence that the portside infrastructure will be ready in time and demonstrate value for money.
Further details on how maritime transport operators or infrastructure investors can register interest are available on the Government Electronic Tenders Service website.
The deadline for written submissions is the end of this month.
Ministers are then expected to take a paper to Cabinet in March outlining which shipyards expressed interest in building the new ships.
Cabinet is also expected to receive an update on alternative proposals at this time and decide whether to proceed with any of those ideas.
A final decision will then be made on the overall approach to procurement.
