On line only, so they reserve my place until they receive my files?
Everyone has to apply online, giving all details of themself and their qualifications and experience (if any), and paying by card. The first 300 people to do this, and who appear to qualify, are told they have a place, then there is a time limit given for them to submit proof. Of course, if they do not reply in time, or they turn out not to be properly qualified after all, they do not get a visa, and this place in the quota becomes available again. (Therefore, even if someone does not get one of the 300 places on the day, it can be worth their time to go back to the Silver Fern page a few weeks/months later, even though the page MAY say that there are no places available, and try to apply - several forum members have done this, and got one of these 'second chance' places.)
So, what career are you thinking of submitting as your skill?
