"We sought the consent to add flexibility but ultimately the plant was always going to close," said Mr Cunningham. The operation had been subject to complaints from nearby residents because of the dust, odour and wool fibres it emitted.
Cavalier Woolscourers was partly owned by Cavalier Corporation whose chief executive Paul Alston said this played no part in the decision to move.
"It was definitely discussed regularly, but from a company point of view the scour had been there for a long time and it was important for our customers and for the country that the wool was scoured.
"Due to the current market conditions it was decided to withdraw from the consent process as the volume coming in could be handled from Awatoto."
He said the drop in wool volume this year was partly due to falling wool prices, and people choosing to hold on to the wool.
"We have got wool coming on stream though - we have exporters and traders who want their wool scoured and we want to do that for them."
Mr Cunningham said the Awatoto plant was fully functioning and consented, so the consolidation would be seamless for customers.
"We just need to fill the plant up.
"We're fully compliant, the infrastructure is all geared up for it - it will be more efficient."
The Whakatu building was owned by a previous shareholder in the company and would go on the market to be sold.
