But Onehunga didn't have things all their own way, and Martin's team was forced fight for their last four debut.
"They were really energetic and were causing us the odd bit of trouble but the message at halftime was to just keep doing the same things because we were creating chances."
"The longer the game went, a little more fitness from our guys and just that little bit better quality created enough chances to get the result. But there was one very scary moment at the end when we just about gave up an equaliser."
With time winding down, Melville's Leon Newell rounded Onehunga goalkeeper Alex Gibson but, from a narrow angle, the striker could only hit the post with his shot as the Hamilton club's chance of reaching back-to-back semi-finals dramatically evaporated.
The remaining three ASB Chatham Cup quarter-finals will be played on Sunday as defending champions Cashmere Technical of Christchurch travel to Dunedin Technical, Island Bay United host Napier City Rovers and Central United entertain Hamilton Wanderers.
