Spokesman Louis Houlbrook said the move "puts serious pressure on their colleagues in Labour and New Zealand First to do the same".
"Transparency around who ministers are cosy with will help to reveal who is really behind government hand-outs or special treatment."
Shaw said the party believed politics should be transparent and its support agreement with Labour included reference to openness and transparency.
"The influence of lobbying and unequal access to politicians is unhealthy in New Zealand politics. We want the public to have more information about our work so we can be held to account and people can learn more about what we are doing in our official capacities."
The diaries show Shaw's meetings included businesses and business groups, energy companies, academics, farming groups, diplomats and the Governor General. Businesses included McDonald's, Z Energy and gas companies as well as a phone conversation with diary giant Synlait.

Shaw also met with church leaders to discuss climate change although the only meetings with Māori groups listed were Ngāi Tahu and the Te Hiku o te Ika group.

Conservation Minister Eugenie Sage's included a meeting with the West Coast waste-to-energy plant Renew Energy and Chinese investors Tianying Inc in June.
