"These detailed plans outline the testing that will need to be completed in order for the plant material to be released if no pests or diseases of concern are found. Once this is done, we're hoping to be in a position to release the apple plants in the near future.
"For stone fruit plants, spring and summer testing will be required so the process will be longer.
MPI also remained open to receiving "modest reimbursement claims" for some direct and verifiable losses incurred as a result of destroyed or contained plant material.
"MPI will also be writing to affected owners early next week to explain the process for submitting the costs and losses they have incurred as a result of destroying or containing their plant material. We intend to offer one-on-one meetings with affected owners to talk through this process."
However, Napier-based Pattullo's Nurseries owner Kerry Sixtus said effected parties were still "very concerned" that some of the innovative plant varieties imported from the United States would not be able to be brought through to commercial production.
"We will continue to fight but the prospect of turning our back on our lifetime's work, burning everything and walking away is still very real. This is not an acceptable outcome."
The group was committed to constructive dialogue with MPI to confirm timelines and would take some time to carefully review and consider the new directions and testing plan, he said.
MPI's original action was taken after an audit found significant failures at a facility screening apple and stonefruit cuttings in the United States.
The order is expected to affect 32 orchardists, nurseries, importers and intellectual property companies in Hawke's Bay, Waikato, Nelson and Central Otago across a range of fruit-based industries, including apples and nectarines.
