National wants to change New Zealand's alcohol laws so vineyards and cellar door wineries are able to charge for samples they are currently required to give away for free.
National also wants to launch a new tourism festival to support domestic tourism and help New Zealand's wineries.
Collins announced the policies at WineWorks in Marlborough this morning.
"Our picturesque wineries are world-renowned tourist attractions and provide huge boosts to the local economies of regions like Marlborough, Hawke's Bay and Central Otago," she said.
