Information and Communications Technology (ICT) spokeswoman Clare Curran's staff accidently emailed the documents to Communications and Information Technology Minister Amy Adams.
One of the documents outlined Labour's potential strategy in the ICT sector.
It included proposals such as a fixed monthly allocation of broadband for every citizen, a Digital Bill of Rights, and a levy on telecommunications companies or internet service providers to fund New Zealand digital content.
Ms Adams said: "Strangely enough, it's the second time they've included me on their internal communications. So maybe they like me, who knows?
"They invited me to a strategy session just after Mr Cunliffe became leader so I'm starting to get a complex.''
The minister said she had only a brief look at the documents but it appeared that Labour's main idea was to start all their policies with the word Kiwi.
Ms Curran's document outlined plans for policies called KiwiMap, KiwiCode, KiwiCall, KiwiCap, KiwiCloud and Kiwis Come Home.
The background notes were for a speech that Mr Cunliffe was scheduled to give yesterday morning.
