The nurse who threw a dildo at Cabinet Minister Steven Joyce at Waitangi and was not charged by police has struck again.

Josie Butler brought a similar squeaky sex toy along to the Government's Trans-Pacific Partnership roadshow in Christchurch yesterday.

She tried to present it to chief TPP negotiator David Walker but was stopped by security staff.

She said: "David Walker, I am here today on behalf of the vast majority of New Zealanders to present you with the New Zealand Dick of the Year Award".

Meeting moderator Sean Plunket told her: "No, you're not."

A security guard took the microphone away from Ms Butler.

He and two other security staff members then escorted her out of the meeting at the Rydges Hotel.

Outside, Ms Butler used a water pistol to squirt an official attending the road show.

She was led away by police.
