Not only has the veterinarian with Vetlife in Oamaru stayed in New Zealand after completing his Massey University studies, but he is one of just 14 males out of his final year class of 86.
He has no regrets staying in New Zealand, being a gender minority or choosing a rural vet practice.
Mr Field (23) along with fellow classmate Claire Patterson (22) have been working at Vetlife for about a month.
Mr Field said he was keen to stay in rural New Zealand because of the variety of work and the quality of people.
He has chosen to deal more with small animals because he likes one-on-one cases rather than the more anonymous situation of treating one cow in a herd.
Most vets graduate with a student loan of between $50,000 and $60,000 after five years' study, which he said encouraged many to go overseas and earn the larger wages available there.
In the last year of Mr Field's class of 86 students, 30% were from Australia, Canada or the United States and, after completing studies, he said about 30 headed overseas.
Many of those who stay in New Zealand would work for a few years, then go abroad, he said.
Mr Field said the gender imbalance in the sector could be due to decisions teenage males were reaching at the end of their school life.
He said he thought they may be favouring apprenticeships or immediately joining the workforce, choosing hands-on activities and the chance to earn money rather than more study.
Male students were quickly contracted in their final year by rural vet practices keen to shore up recruits, he said.
Mr Field was still to decide if he would specialise in surgery or focus on animal behaviour.
