Tasmanian Greens leader Cassy O'Connor has hit back after being removed as the head of the committee examining the state's greyhound industry.

The decision came after Ms O'Connor spoke in support of abolishing the industry at an anti-greyhound rally in Hobart earlier this month.

After refusing to comment yesterday, the Greens leader was unapologetic on 936 ABC Hobart this morning.

"I'm not sorry I spoke at that rally," she said.

"Any member of any parliamentary committee is entitled to express a point of view about the matter that's before the committee.

"I was not speaking as the chair of the committee.

"Nobody should be surprised by my view on this industry, which has grotesque cruelty at its heart."

The committee voted yesterday to remove Ms O'Connor as the chairwoman.

The new chair independent MLC Adriana Taylor said yesterday the move was made in the interests of the committee's impartiality.

Ms O'Connor said she was asked to step down but refused.

"I declined to do that because I truly believe I've done nothing wrong," she said.

"I've [tried] really hard to be fair in the chair.

"Anyone who was surprised by anything that was said at that rally hasn't being paying attention for the past year."

It is understood the vote was 6-2 in favour of her removal.

Defiant to the end, Ms O'Connor reiterated her long-held view on greyhound racing.

"This is taxpayer-funded animal cruelty," she said.

The committee will hand down its report at the end of March.

Ms O'Connor will remain as a member of the committee.
