National's Nicola Willis is ready to get stuck in after receiving her ministerial warrant.

The newly sworn in Finance Minister plans to spend her first few days working on fiscal and economic updates in order to address the current economic climate.

She says the outgoing Labour Government left her with several fiscal cliffs and risks to mitigate.

"There's programs that they had ongoing that they just hadn't put money into for the future that realistically, we're going to have to find the money to fund."
