Former mill operator Sam Simpkins had worked at the mill for nearly 30 years.
"It was a huge shock. I have been here for 30 years. It's devastating for the area. There used to be 15 mills down here.
"I am of retiring age, but I still feel I can put in a good day's work. I am weighing up my options but I will probably look for work elsewhere."
Mr Simpkins was not concerned about finding another job at a mill in the area.
The company has organised for local recruitment agencies to help prepare CVs for any employees at no cost, and has arranged for Work and Income staff to be on site to assist workers with financial and job search assistance.
Workers will receive their normal pay until April 8. However, production at the sawmill will end next Tuesday.
Engineering Printing and Manufacturing Union (EPMU) organiser Red Middlemiss said the company had been a good employer.
"This business has never been about them and us and they have been a good employer. Still, it's outside circumstances that have made them shut down. They are doing their best.
"A lot of the guys already have jobs, which makes it a little bit less painful."
He blamed the current economic climate for the closure.
"It is lack of foresight by successive governments, that's all it is. They sold off all of our forests, so it loses that personal contact. No one cares about the workers. They just want to know that the logs are coming out.
"We've negotiated that the non-union members get the payout as well."
Mamaku Sawmill owners would meet with workers again today, Mr Middlemiss said.
