The Government is being asked to make sure fire service personnel are fully involved in the merger of the country's fire services.

Internal affairs minister Peter Dunne has announced a $303 million plan to merge the Fire Service, rural and volunteer fire brigades over the next four years.

The establishment of the new Fire and Emergency New Zealand agency isn't expected to lead to job cuts, or affect the pay and conditions of workers.

Glenn Barclay, the national secretary of the Public Service Association union that represents fire personnel, said staff are pleased with the assurances they have received so far.

"We think that the process looks like it is as good as these highly disruptive processes can be, but we just want to be involved."

Mr Barclay said he hopes the reform process will be done quickly to allow staff to get on with their jobs.

"Any restructuring or review is unsettling for staff. We are pleased that the Minister has given a commitment not to cut jobs and to keep all employee's entitlements. That means a lot to our members."

Mr Barclay said the long-term impact of the restructure on corporate and administrative staff remains unclear.

He said staff are hoping the process will continue to be transparent.
