So when they ended up in Randalstown outside a pawn shop they decided to go in and look for one of James Agnew's clocks.
But the shop owner did not recognise the name, nor did he have any in his shop.
He did, however, have an old grandfather clock which had been sitting out the back.
And there it was - a "huge" clock built by Mr Agnew's great great grandfather.
"The miracle of finding the clock was quite stunning," Mr Agnew said.
The trouble was, the huge clock was 17,700km away. But Mr Agnew was determined to get the clock "by hook or by crook".
So it was bundled up and flown all the way to his home in Porirua.
"It wasn't going to slip through my fingers."
He now hoped the clock would become a family heirloom. A coin would have to be tossed to decide which of his three children, who all wanted it, got it, he said.
However one family member is not so fond of the clock. "It makes a hell of a noise - my wife doesn't like it because it makes too much noise."
