Goldsmith suggested businesses would need to prove they needed the subsidy, without giving details.
He named the tourism, hospitality and forestry sectors, but was unclear on whether National believed the subsidies should be nationwide or specific to certain regions.
"What they need to demonstrate is a clear impact upon their businesses and there'll be criteria around that but the Government needs to work out [the criteria]," Goldsmith said.
"What we don't want to see is businesses falling over because of what we hope is a short-term economic shock and people losing their jobs and being thrown onto benefits."
The targeted relief Goldsmith suggests is already under consideration by the Government, after BusinessNZ made a call for such a move at a meeting with Prime Minister Jacinda Ardern and Finance Minister Grant Robertson on Monday.
During Question Time in Parliament, Robertson repeated that measures to keep businesses operating were a focus.
"There are a range of measures we can undertake to keep people in work, that is most definitely our focus at this time."
Goldsmith's call also marks something of a change of focus by National.
Earlier in the week National's leader Simon Bridges said the Government should look to immediate tax cuts.
Goldsmith meanwhile told the Herald that tax reform was not such an immediate pressure.
"Long-term tax relief is certainly part of the mix."
