Hamilton's IRD building.
The exodus of 500 IRD staff from Hamilton's central business district to Te Rapa has been put on hold until late 2018.
An IRD spokesperson said when the request for proposals was released to the market in August last year there was an expected timeframe set for a move by
the end of 2017.
"I can confirm that the two remaining tenders are for sites in the Te Rapa area and that Inland Revenue will continue to occupy our premises in Bryce St until late 2018."
The spokesperson could not say whether the Te Rapa sites had existing building on them or would require a new build.
"That is commercially sensitive information," they said.
