New Zealand Post has confirmed 90 jobs will be lost when it closes its Waikato mail processing centre.
Last June NZ Post announced it was closing its Waikato, Wellington and Dunedin mail centres, at a cost of 500 jobs in total.
Engineering, printing and Manufacturing Union (EPMU) postal industry organiser Joe Gallagher said closing the Waikato mail centre would impact the whole community.
"The fact is that Post is still very profitable, but the government has given them permission to reduce delivery days, reduce the level of service provided to the community, and cut jobs up and down the country," said Mr Gallagher.
"It's really disappointing that we have a government more interested in building new roads than investing in jobs and regional development."
EPMU members at NZ Post would be entitled to redundancy pay under their collective agreement.
