Krūmiņa was voted in with 89 votes for and none against. It had been clear prior to her appointment that there'd be no competition for the office.
Her current term runs out on January 23. She enjoyed support both among opposition parties and high-ranking figures such as the president and prime minister.
"We will most definitely give more attention to municipalities, so that we can help residents get good and fair-priced services," she said upon being re-elected.
Previously Krūmiņa told Latvian Radio that, if re-elected, she would focus on efficiency audits and the lawful use of state funds.
The Auditor General is elected by the parliament for a four-year term and cannot remain in office for more than two successive terms.
