Greene (19), a food science student at the University of Otago, needs a big improvement in her specialist 1500m to get to Glasgow.
Her best time is the 4min 18.15sec she ran in Watford, England, in June when she was preparing for the World University Games in Russia. But she still has a big hurdle in front of her to reach the New Zealand B standard of 4min 9sec to qualify for Glasgow.
The A standard is 4min 5.50sec.
Greene plans to race 400m and 800m races in the pre-Christmas period to develop her speed.
She set an Otago senior women's record of 4min 18.90sec when qualifying for the final at the world junior championships in Moncton, Canada, in 2010.
But she has plateaued over the past three years and her rate of improvement has been fairly static. However, this is standard for an athlete of her age.
Do not rule out a sudden breakthrough this summer. Greene will be ready to knock at least 8sec off her best time.
Her times for other events suggest she is poised for a big breakthrough: 400m (57.8sec), 800m (2min 7.12sec), 3000m (9min 21.23sec).
Greene was given a hard lesson at the World University Games in Kazan when she failed to qualify for the final of the 1500m.
''I was pleased with races leading up to it but on the day it was a bit hard. It was a really slow race and they took off on the last lap,'' Greene said.
''I haven't quite got used to that.''
Greene is recovering from an Achilles tendon problem and has not been able to train over the past month, but she expects to be back racing at the Caledonian Ground in the next few weeks.
Greene competed internationally for the first time at the Pacific Schools Games in Canberra when she was aged 14 and won the 3000m in her age-group.
She was second in the 3000m at the Australian Youth Olympics in Sydney a month later.
In 2010, at the age of 16, she finished second in the senior girls cross-country at the world secondary schools championships in Slovakia.
Greene contested her second world junior track championships in Barcelona last year and finished seventh in the 3000m but failed to make the final in the 1500m.
Greene has been hand-picked by Athletics New Zealand and is in the high performance development group preparing for the Rio de Janeiro Olympic Games in 2016.
''The experience I have had helps a lot,'' she said.
''I know how to prepare for the races. It is good to see what the standards are like.''
But there are pitfalls.
''I have a summer season in New Zealand and then have to prepare for the track in the winter,'' she said.
''I have not had a winter training for a long time. It's been a bit of a pain.''
