The 28-year-old all-rounder was placed in an induced coma after being admitted to hospital having suffered multiple injuries, including a fractured skull, following a late-night assault outside a Christchurch bar.
O'Brien was speaking after being updated with Ryder's latest condition by New Zealand Cricket Players' Association (NZCPA) chief executive Heath Mills, who had travelled to Christchurch along with New Zealand Cricket chief executive David White, Peter Clinton from Cricket Wellington and Ryder's manager Aaron Klee.
O'Brien said: "He's still the same.
"He's in the induced coma and they tend to keep them in that state for anything up to a couple of weeks depending on the brain swelling. You have to keep them as still and as quiet as possible.
"There's no brain damage, from early reports, which is great news, so in terms of a recovery, in terms of the kind of person he'll be afterwards, fingers crossed he comes out as as similar-natured bloke."
Ryder was in Christchurch playing for the Wellington Firebirds and he had been dismissed for a duck earlier in the day in their 61-run Ford Trophy semi-final defeat at the hands of the Wizards.
He was due to head off to the Indian Premier League soon with the Delhi Daredevils having recently spent NZ$307,000 in their player auction to sign him for the 2013 edition.
The 28-year-old is in a self-imposed exile from international cricket and has not featured for the Black Caps since February 2012, missing the entirety of the recent series with England.
Detective senior sergeant Brian Archer explained Ryder was involved in a brief altercation "two or three" people when he left the bar but was then attacked by one of the individuals after he crossed the road to a nearby fast-food outlet.
"The hospital advise he is in a critical condition. He is in an induced coma as a result of suffering multiple injuries."
Ryder, a controversial figure whose career has been plagued by off-field incidents, has played 18 Tests and 39 one-day internationals for the Black Caps.
He has a Test average of 40.93 and a highest score of 201.
