The mill will continue to operate with no restrictions until the certificate had been received.
The Rotorua Lakes Council received 64 complaints overnight relating to noise issues from the Eastside industrial zone.
On Monday night Steve Chadwick, deputy mayor Dave Donaldson and Rotorua Lakes Council staff and compliance teams observed first-hand the noise concerns being raised around the Eastside industrial area and in particular the Lumbercube mill on Vaughan Rd.
Overnight Monday there were a further 91 noise complaints lodged, bringing the total number received since the mill opened in September to 1472.
About 40 people took to the street outside the mill last week to protest against the noise they say is keeping them awake at night. They say the noise issues have escalated since the mill started operating at night in March.
Pressure has been mounting in the eastern suburbs since the mill opened, with some locals calling for the council to shut the mill down.
The Eastside Residents Action Group has been set up to take on the council over noise issues and was planning to set up an incorporated society.
Lumbercube management have told the Rotorua Daily Post it was doing everything it could to reduce the noise and had spent around $1.7 million on the problem.
