The hosts took a 2-0 lead in the first half through goals from Ellis Sellars and Aiden McCallion, but a Sam Foy double levelled it for Josh Bowmaker's troops.
Newlands regained the lead five minutes from time through a McCallion free-kick which bounced through the Scalby defence, capping a fine game from both teams.
Bowmaker said: "Max Edwards was man of the match at centre-back but the whole team was excellent in the second half for our battling performance."
McCallion was named as the man of the match for the triumphant Newlands side.
Filey Town Reserves worked hard for a 5-1 home win against an improved Ayton Reserves outfit.
In a keenly-fought first half it took Town until the 35th minute to open the scoring through Joe Gage, who finished neatly after latching onto a long through-ball.
Joe Gage doubled Filey's lead in the first minute of the second half, despite protests from the visitors that the ball had gone out of play in the build-up.
Sub Lee Lambert made sure of the win with a goal on the hour mark, James Smith adding a fourth to boost their advantage.
Ayton pulled a goal back late on when Nicko Dunn and Dan Bywater combined to set up Chris Milburn to score, but Max Gage's header, with the last meaningful action of the game, restored their four-goal lead.
Defender Josh Westmoreland was named as the man of the match for the home side, with central midfield duo Nathan Robson and Max Gage also impressing for Dan Kempson's team.
William Jones had an outstanding game at centre-back for Ayton, while youngster Christian Reddish also played well.
