[5][6] After Sigbjørn Gjelsvik was appointed minister of local government, Pollestad became his successor as the party's financial spokesperson on 27 April 2022.

[9] On 31 January 2023, he became acting chair of the Standing Committee on Finance and Economic Affairs during Eigil Knutsen's leave.

[10] Following his party's withdrawal from government, Pollestad again became deputy parliamentary leader and also joined the Standing Committee on Finance and Economic Affairs.

[11] In 2007, during the reign of Stoltenberg's Second Cabinet, Pollestad was appointed political advisor in the Ministry of Local Government and Regional Development.

[13] Shortly after assuming office, Pollestad and finance minister Trygve Slagsvold Vedum announced that the government would re-establish emergency storage facilities for grain, marking the first time in over 20 years the country would be doing so.

[15] Pollestad later confirmed that the Ministry of Justice and Public Security's legal department would look into whether or not he would be considered non-impartial on delicate issues.

[18] The following month he received criticism from fellow cabinet member Andreas Bjelland Eriksen about destroying nature in favour of big projects.

In September 2024, the legal department at the Ministry of Justice and Public Security concluded that Pollestad was impartial, reasoning that "a slight personal reluctance is not considered sufficient".

Pollestad argued that he could not put focus on local made dough, blaming the EEA agreement preventing him from increasing tolls on foreign products.

[23] The government, with the support of the Liberal Party, Christian Democrats and Patient Focus, secured a majority in parliament in February to approve the political premises of the numerical basis for the 2024 agricultural settlement.

Pollestad praised the agreement and emphasised the importance of reaching it in relation to increasing income opportunities and other achievement of goals in agricultural policy.
