Internet Party Leader Laila Harré will stand against Prime Minister John Key in his Helensville electorate, she said this evening.
She was standing against Mr Key "because the Prime Minister has some explaining to do" and she wanted to debate him at candidate meetings "away from his army of spin doctors".
She would be asking him "to explain his Government's relationship with Hollywood and Skycity".
"I'll be asking him to tell us what's in the TPPA he is negotiating behind closed doors and to open the books on our intelligence relationships."
Ms Harré also said she would be taking Mr Key to task over the economy.
