"I share the public's frustration, but it is important that we get this legislation right so that we can have a future-proof framework ready to present to Parliament," Associate Health Minister Jenny Salesa said in a statement.
"Seeing this legislation introduced is a priority for me. I have been working towards introducing a bill this parliamentary term and that remains my goal," she said.
But in a statement to 1 NEWS in May, Mrs Salesa said she expected the bill to be introduced in August.
Then in September, a statement said that legislation was due to be introduced in the next few weeks.
