Federal Labor says it will be involved in the royal commission into its home insulation scheme but it wants to make sure the inquiry is aimed at improving safety, and is not a political game.
Opposition Leader Bill Shorten said the terms of reference needed to be bipartisan.
The commission will investigate whether the practices of the government at the time contributed to four deaths and extensive property damage in the wake of the scheme.
The $2.8 billion "pink batts" program was implemented by then-prime minister Kevin Rudd to inject money into the economy during the global financial crisis.
Mr Shorten would not be drawn on whether he thought Mr Rudd should appear before the inquiry, which is due to begin hearings before Christmas.

"Health and safety should be the focus of the government, not whether or not the government wants to square off with Kevin Rudd," Mr Shorten told reporters in Melbourne on Friday.
"We believe if it's a royal commission aimed at improving safety then of course we'll always be involved.
"But we want it to be bipartisan in terms of the terms of reference."
He said all parties should work together to ensure that sort of thing never happened again.
A Queensland coroner in July found the rushed rollout of the scheme was a significant factor in the deaths of three Queensland batts installers.
A NSW installer also died on his first day on the job.
