National's fiscal and economic plan may have been blown out by another $3.9 billion after another miscalculation appears to have been found.
Stuff has revealed it appears National has double-counted part of its infrastructure upgrade programme, but National Party finance spokesperson Paul Goldsmith has denied the mistake.
This comes after the party made an error on Sunday resulting in a $4 billion fiscal hole and another mistake on Monday resulting in another shortfall of $88 million.
On Tuesday Stuff revealed National appears to have made an error in counting the $3.9 billion left over from the New Zealand Upgrade Programme twice.
The programme was announced in January with the party planning upgrades towards rail, roading and public transport in New Zealand's six main growth areas.
There was left over money from the programme which was put into the Treasury's multi-year capital allowance in May, Stuff reported.
But in National's fiscal plan which was released ahead of the upcoming 2020 Election, the party counted the leftover money as if it was in both places.
The party now appears to have another shortfall of $3.9 billion, but Goldsmith has denied the mistake.
He told Stuff he left the line for "consistency" with an earlier National plan.
He said the missing billions of dollars will come from reallocating money collected in fuel taxes and road user charges in the National Land Transport Fund (NLTF).
