The government is fronting up another $25 million to assist businesses in the clean-up from Cyclone Gabrielle.
It brings the total business support package to more than $75m so far.
In a statement, Finance Minister Grant Robertson said demand for grants had been strong, with about 5800 applications received.
"The priority has been to get businesses back up and running as quickly as possible from the impact of the cyclone, working through the local agencies on the ground who know their area best," Robertson said.
Businesses can apply through local providers for up to $40,000 in support. All applications for funding will close no later than the end of April.
"The split of this additional funding between regions will be based on the latest available data. Ministers are committed to ensuring that it is focused on those regions where the need is greatest," Robertson said.
The government was fully commited to the cyclone recovery, he said.
"The way we do that will change as we shift from the response to recovery phase.
"We will continue to closely monitor the needs of local communities and work with local agencies, iwi and councils as we move from response to the recovery and rebuild from these extreme weather events."
