Inland Revenue has confirmed details of a major restructure after closing early today.
The Public Service Association, the union that represents government workers, said it has "serious concerns" for staff after IRD announced its final decision document on its proposed business transformation, which the union believes could affect up to 4000 staff in the organisation.
"The final decision document - which provides little transparency regarding possible reductions in staffing levels - indicates that organisational changes will be made from February 2018, with the rollout of Stage 2 of IRD's computer system changes beginning just 2 months later," said PSA spokeswoman Erin Polaczuk.
"The loss of expert staff and the lack of certainty for workers reapplying for more simplistically modified roles means that important regulatory changes to the tax system rest on very shaky foundations," Polaczuk said.
"This could affect up to 4000 staff in varying ways at this stage of the restructure, and this has not been fully explained," she said.
