Ardern gave a TEDx-style talk in Auckland in September, alongside Coalition partners New Zealand First and the Green Party, to launch the 12 priorities, a blueprint for the country.
She promised to report back to the public regularly on how they were progressing, with the first update due this month.
But it emerged this week that the Government had to start from scratch on some indicators, holding things up, because some priority areas weren't currently measured.
Today Ardern confirmed the indicators would be ready to go next month.
A spokesman for Ardern told the Herald last week that the first update had been delayed because at the time the work was begun on delivering the 12 priorities, it was realised there was a range of things that weren't measured.
"We have had to create some new indicators which has slowed down their public release," the spokesman said.
As well as the 36 indicators, a progress report and the first review of the work programme are also expected to be released soon.
