The payments by their nature - responding to rising costs - would have had to be organised with some urgency. A key decision was to make it easy for people to receive the money rather than invite people to apply, which meant reliance on the Inland Revenue Department's data.
Ardern said IRD had issues to work through with the first batch. The second round of three payments is due tomorrow.
The PM, who said it was impossible to design a perfect system when trying to reach 2.1 million people, took issue with the idea that there was a lack of clarity over who was eligible, saying IRD was told to pay residents in the country.
Ryan was critical of both the Cabinet and IRD, summing up the situation as "speed and expediency were prioritised over certainty and accuracy".
Despite the way it's been handled, it still amounts to financial help to a lot of people and sits alongside other efforts such as fuel tax cuts.
However, any governing party - especially one facing an election next year - wants a reputation as being generally competent and a good manager of finances.
This incident has given National's finance spokeswoman Nicola Willis the opportunity to describe the process as "rushed" while the Government scrambled to tweak eligibility checks.
Throughout the first two years of the pandemic, the Government was similarly often reactive to criticism over Covid measures and approaches, making adjustments as it went along, which at least was better than not being flexible enough to do so. But that leaves the frustration of not getting things right in the first place.
The pandemic's impact ran through a strike over pay disparity between community and hospital nurses.
New Zealand Nurses Organisation president Anne Daniels said of community nurses: "They were the frontline during the Covid outbreaks, doing the vaccinations and the testing".
Staffing shortages, residency issues and the cost-of-living crisis make the health sector a particular area of pressure for the Government.
Labour has at least managed to insert some distance into the ongoing saga of now-independent MP Gaurav Sharma after he was expelled from the party. But a lengthy Facebook post by the MP suggests it will drag on.
The Government can only hope for less turbulence ahead.
