Winston Peters' lawyer has changed his story to Parliament's Privileges Committee.

Brian Henry concedes Mr Peters was the client he referred to in an email to Owen Glenn, something he had previously denied.

Mr Henry remains positive however he solicited the $100,000 donation. He says he thought of doing so in a phone call with Mr Peters after he told him he had talked with Mr Glenn.

"That jogged my memory and then sent an email to try and jog Mr Glenn's memory in the hop we'd get a donation."

When asked if it was pure coincidence, Mr Henry replied "that's just what happened".

Mr Henry says Mr Peters never mentioned money in the phone call.
