Treasury officials suggested halting the expansion of the national bowel screening programme as an option to keep Health Minister David Clark's Budget 2018 wish-list within the $750 million to $770 million range, newly released documents show.
The advice, contained in a report to Clark and Finance Minister Grant Robertson in early March, was released in a large tranche of Budget documents by Treasury on Thursday.
The advice came with warnings of negative outcomes for patients and damage to the Government's reputation if the rollout did not go ahead.
The advice was not taken up, with $67.1m funding in this year's Budget to extend the programme from five district health boards to 10.
The Treasury report outlined "key trade-offs" that could be made to keep the health portfolio spend within budget and gave Clark and Robertson four options to achieve it.
