Neither side could complain with the result though and both were guilty of spurning golden scoring opportunities during the game.
Merrick made an interesting change at halftime as he yanked striker Paul Ifill and inserted Spanish midfielder Albert Riera.
The thinking behind the decision from Merrick was so he could plug the midfield with another body after Newcastle had enjoyed a string of possession in that area during the first 45 minutes.
Newcastle played a pressing style on defence as they looked to limit Wellington's time on the ball.
Wellington's players had little time to react as the Jets scurried around McLean Park at a rapid rate of knots as they aimed to shut down the Phoenix.
The ploy worked for the opening half an hour in particular as the Phoenix struggled to find their way in the to game.
Bar an exciting strike from Carlos Hernandez, which rattled the crossbar in the sixth minute, Newcastle enjoyed the better of the opening stages.
Youngster Andrew Hoole had plenty of time to line up a shot on goal but could only sting the palms of Phoenix goalkeeper Glen Moss, while Ruben Zadkovich hit the crossbar in the 20th minute from a free kick.
After Zadkovich's shot rattled the bar, Moss made a brilliant follow-up save before Leo Bertos then cleared the ball off the line in a mad-cap sequence, where the Jets seemed destined to score.
Playing at such a high-octane pace on defence was sapping for the Jets though and Wellington eventually wore them down and enjoyed a prosperous period during the back end of the first stanza.
Striker Stein Huysegems should have scored from close range in the 43rd minute but his header was expertly saved by Jets custodian Mark Birighitti.
Birighitti was again at the heart of the action mid-way through the second spell when Phoenix skipper Andrew Durante had a shot blocked from close range by the Newcastle gloveman.
Only moments later, Birighitti was then caught off his line as he came for a cross and didn't make any contact with the ball but Hernandez could only hit the post with his off-balance, left-foot shot with the goal at his mercy.
Eventually both sides seemed pleased with a point as the game meandered to it's death.
