Trustee chairperson Nicky McArthur said protecting the night sky would bring benefits for human health, the environment and biodiversity.
"We have forgotten the awe and wonder of a truly beautiful night sky.
"If by becoming a dark sky sanctuary, we are also providing a platform for economic benefit to the region it should be a win for all."
Dark sky sanctuaries have already been created at Great Barrier Island and Rakiura/Stewart Island, while dark sky reserves have been established in Wairarapa and Aoraki Mackenzie.
With more dark sky projects in the pipeline, including a possible Oxford dark sky community, New Zealand was well on the way to becoming a dark sky nation, McArthur said.
She said the trust would be busy this year working on community outreach and awareness, alongside the formal work towards accreditation.
It would require a private plan change request to the Kaikōura District Plan.
Trustee Brian Horsfall said the trust would be visiting schools from next month and organising public evenings.
"We just want to get people looking up and to start valuing the skies we've got."
Stargazing evenings will be held monthly at the Kaikōura Lookout, 274 Scarborough Street, from Friday, 21 April.
The trust's website, kaikouradarksky.nz, has stargazing tips, rise and set times for the moon, and resources for astronomy education, or like Kaikoura Dark Sky Reserve on Facebook to keep up to date.
