A minute's silence will be observed in Greymouth on Thursday to mark the 50th anniversary of the 1967 Strongman Mine disaster which claimed 19 lives.
The Last Post will also sound on Saturday at the memorial at Nine Mile, on the Coast Road, as part of the commemorations and reunion, with 200 people registered to attend, largely family members, surviving rescue team members, former colleagues and others associated with the mine.
Two services will be held in Greymouth, organised by the 50th commemoration committee and Greymouth Churches Ministers Group.
On Thursday a small informal service will be held at the mass gravesite at the Karoro Lawn Cemetery.
