"During a conversation lasting almost 10 minutes ''Ruby'' quizzed Mr Shadbolt on the talkback show about the community benefits of the planned Auckland to Bluff yacht race and who would pay for the race expenses, including the infrastructure needed to moor up to 30 super and maxi yachts at Bluff.
About eight minutes into the conversation, Mr Shadbolt appeared to rumble her, calling her Ali, to which she replied, ''Sorry, who? This is Ruby here.''
Mr Shadbolt said he was ''very suspicious'' from the start that Ruby was Cr Timms but did not want to denounce her on air in case he was wrong.
''I threw in Ali twice to give her an escape, but she was quite adamant she was Ruby. If she had said `fair enough, it's me', that would have been a joke, but she didn't.''
