There r generally more jobs available in Auckland than out of it. Besides Auckland is the financial centre, so it will be here if you are looking for financial related jobs. If you have problem getting a job, you might want to go through other channels instead. Like talking to recruiters directly, talking to HR in companies that you are keen to apply to even if there is no job vacancies, connect around outside your current circles with locals or other kiwis who may have contacts here and there that could help.
