Constables Duncan Hollebon and Brenton Rooney were found guilty at trial in June last year of assaulting a man while attempting to restrain him in February 2009.
The Court of Appeal later rejected their appeal against their convictions.
After their criminal trial, which started more than a year after the assault incident, the men went through the police internal disciplinary process, including a disciplinary hearing in January.
Police human resources general manager Brendan Keys said the men, who were suspended the day after the assault incident, remained "suspended on full pay in accordance with disciplinary processes pending resolution of an employment-related investigation".
The salary band for a constable ranges from $58,004 to $84,062 a year, meaning the men have been paid at least $145,000 each since they were suspended.
While it has previously been reported that police officers suspended on full pay also retained their full entitlement under their employment conditions, Mr Keys said each case was treated on its merit and took into account individual circumstances.
He said it would be inappropriate at this stage to discuss any details of the ongoing employment matter, or why it was taking this long to resolve.
He declined to answer questions about whether the officers had been offered other jobs within the police - a common outcome in the police disciplinary process.
Police Minister Judith Collins said she could not comment on individual cases, or the police employment process.
Auckland employment relations specialist Max Whitehead said he had 20 years' experience in employment law and it was "extremely" unusual for someone to be suspended for two and a-half years without the matter being resolved.
"To me, the only time you ever hear about it is when the police do these lengthy suspensions, which would be unpracticable in any other business."
Police association president Greg O'Connor said he could not comment on this specific case.
But long suspensions were the price the public paid for a police force that was exceptionally hard on its own, and had to be because it was the only organisation in the country that was both the employer and the prosecutor.
Police were "very afraid" of being accused of looking after their own and employees were often charged with criminal offences for actions that would only be considered an internal employment issue by other employers.
The police processes were the way they were to make sure employees were fairly treated in such a system, and had to be followed properly.
If they were not, it would ultimately be more costly for the taxpayer, he said.
