The Government is under renewed pressure to reinstate check inspectors in mines, following an underground fire at a goldmine near Waihi on Tuesday.
A truck engine caught alight inside the Trio mine at 5am on Tuesday, and it was seven hours before all 28 men in the mine were safely back above ground.
A check inspector is an experienced miner who can order an immediate withdrawal from a mine.
Labour says they are considered the international benchmark in mine safety and the Government should urgently introduce them.
The Government says a decision on reinstating check inspectors will be made after the Pike River Royal Commission reports in September.
