The latter was largely due to a $146,754 pay out from the privatisation of the Blues' franchise.
Parkinson attributed the smaller profit to a decrease in income and ACC levies for Super Rugby players contracted to the Taniwha.
He said Super Rugby players like Dan Bowden, Dan Pryor, and Jone Macilai who were injured last year were not entitled to ACC levies because they were self-insured.
"We also employed three additional rugby development officers in Whangarei and the Bay of Islands on short-term contracts so that was another expense for us," he said.
The union's audited accounts for 2015 was presented at its annual general meeting at Toll Stadium on Wednesday evening. Parkinson said NRU delivered on key performance indicators by being one of 12 provinces out of 26 that grew teenage participation in the game with a 5 per cent increase in the 13- to 20-year age bracket.
He said 79 more teenagers played rugby in Northland in 2015 than in previous years.
This year, Parkinson said the union's main focus was on making the Taniwha competitive for the Mitre 10 Cup.
A combination of factors - some unforced - created a "perfect storm" for the team last season.
The Taniwha had lost 10 key players and new mentors, including head coach Richie Harris, started late with the team.
Wing Jone Macilai turned up unfit, out of shape, and in poor form while Dan Pryor missed all but seven games due to injury. Injuries in other key positions like tighthead prop had not helped either.
