根据移民局最新消息，下期假期工签发放时间确定为新西兰时间2010年7月5日上午10点整，发放名额数量为250个。

以下内容源引自新西兰移民局官方网站：

250 places will become available from 10 am New Zealand time, on 5 July 2010. As with many of our working holiday schemes, the interest from potential applicants is expected to be much greater than the number of places available. This can result in the quota being filled within hours of it opening, and may mean that many people miss out.
