Swarbrick said the inquiry would provide "insights for the remaining stages of this pandemic and to respond to future economic challenges."
"We are two years into the pandemic and Covid-19 and the Government's response to it have had clear macroeconomic impacts. While our unemployment levels are low, house prices and rents have skyrocketed.
"Banks and supermarkets have reported record profits while renters, students and those with precarious incomes have felt the disproportionate impact of global inflation," she said.
Swarbrick has previously wanted an inquiry into the economic response, but one conducted by the Government, rather than a Parliamentary select committee.
But Finance Minister Grant Robertson said "a more comprehensive evaluation" of the economic response would "be considered once we are beyond the current phase of the pandemic".
