The Government is signing off on three concept plans for re-entry into Pike River mine.
Minister in charge Andrew Little outlined the proposals from the Recovery Agency to West Coast families last weekend.
The options include building a new 2m by 2m tunnel, drilling a large borehole and or re-entering from the main drift.
"Recovery of the mine drift is technically feasible and the risks of harm can be managed and minimised," said Mr Little.

Detailed plans are now underway, including a procurement process, with an update expected in October. Re-entry efforts may begin before the end of 2018.
