Emails released to RNZ show a US offer to rapidly set up Covid-19 data-crunching capabilities sat with the government for more than a month during the lockdown period.
The offer came from Silicon Valley company Palantir, controversial for its links to spy services in the Five Eyes network New Zealand belongs to.
The emails showed the Customs Department put Palantir in touch with the Ministry of Health.
The company told the ministry in March it knew agencies in New Zealand were "under strain".
