The seven men and seven women sent to tournaments in Wales and Scotland last winter have the edge.
''They have the advantage because they have experienced the Glasgow greens,'' national coach Dave Edwards told the Otago Daily Times during the North East Valley singles.
But form in the New Zealand season will still count.
''If two or three people are vying for one position, those who show form in New Zealand will enhance their chances. Bowlers need to keep sticking their names in front of our noses.''
Set play was used for the Commonwealth Games in Delhi but Glasgow will go back to the traditional format of 15 ends for pairs, triples and fours, and 21 shots for singles.
Val Smith's silver in the women's singles was the only New Zealand bowls medal won in Delhi.
''We are aiming for four medals at Glasgow, and we'd like at least one of them to be gold,'' Edwards said.
''The northern hemisphere countries will be difficult and South Africa and Singapore also play on slow greens. Australia will be tough.''
Bowls New Zealand has established a slow green at Glasgow speed in Auckland for the Black Jacks to train on during a series of weekend camps before the Commonwealth Games.
The Black Jacks will arrive in Glasgow 10 days before the Commonwealth Games begin, to get match play against tough opposition. It is important they get good results next year.
''There are lots of sports fighting for dollars of campaign funding from High Performance Sport New Zealand,'' Edwards said.
''It is important for us to perform for our future funding aspirations. People want to see results.''
It took the New Zealanders time to get used to the slower greens in Wales and Scotland. The greens run from 10sec to 12sec compared with the faster 16sec to 18sec greens of New Zealand.
''We were happy by the end of the tour,'' Edwards said.
''The hard work they had done on the croquet lawns in New Zealand had tuned them up.''
''By the end of the tour all 14 players were hitting their straps and had got used to the greens and the style of play needed.
''In New Zealand you draw to the jack. Up there, you play at the jack, which is always on the move.''
A run at the jack on a New Zealand green springs the jack in all directions. On a slow northern hemisphere green, the jack will move just 12cm.
Northern hemisphere bowlers always play at the head and through the head.
''We hate short bowls on our faster greens but up there, a short bowl is a big no-no,'' Edwards said.
