Prime Minister Christopher Luxon is doing the media rounds this morning, following last week’s visit to Fieldays - and his party’s Finance Minister accusing Labour of being billions of dollars short in funding its policy proposals.Nicola Willis said there was a $18.2b “yawning gap” between Labour’s policies and the money available to fund them.Labour has called the move “desperate”, saying it shows National is concerned about its own fiscal plans.The PM will appear on Newstalk ZB’s Mike Hosking Breakfast at 7.37am. You can listen here and watch the livestream above.Luxon was at Fieldays last Wednesday courting the agricultural community, with promises of up to $51m to help roll out emissions-reducing tech on farms and $59m going into six land-based commercial projects.He also said the coalition Government’s position was for New Zealand to remain in the Paris Agreement, and would do everything it could for the country to reach its international climate commitments. However the Government would not be sending “billions of dollars” off shore to do so.Fieldays also saw National’s coalition partner NZ First dialling up its attacks on the party, with a fiery speech from leader Winston Peters in which he distanced himself from the PM on climate issues and suggested farmers should start voting for NZ First as “insurance”.He slammed National for signing up to “stupid” climate targets and attacked the Indian Free Trade Agreement, as well as blaming the party for the Resource Management Act.Also in attendance were new NZ First candidates Stuart Nash, the former Labour minister, former All Black Taine Randell, an ex-National minister Alfred Ngaro.Nash told the Herald the difference to working with Labour is that while Labour may set up “working groups” and “consider things”, NZ First “is the party that does stuff”.Controversy is also still swirling around the announcement of Labour’s candidate list, with Police Superintendent Rakesh Naidoo facing heat after it was announced he was 13th on the party’s list.Naidoo had been in conversations with Labour for months, but only told his supervisor two weeks ago of his plans to stand for the party.National MP and Police Minister Mark Mitchell raised concerns that Naidoo had access to sensitive information, swiftly followed by similar comments from Police Commissioner Richard Chambers.Labour’s police spokeswoman Ginny Andersen then accusing Mitchell of telling Chambers what to say, alleging he had violated police’s independence.Mitchell and the Prime Minister have both denied any collusion with Chambers.
