奥克兰公交卡 AT Hop 里的余额有效期是多久？
AT Hop 卡是不能退换卡中的余额以及购卡本身的费用（十元一张的卡费），预充值在里面的钱，持卡人只能够选择花掉或者转移到另一张新卡中（如果旧卡损坏了）。不过，反正奥克兰的公交资费挺贵的，就算AT HOP卡里面有300块（最高充值额度）用掉也就是几个月时间的问题。或者可以把卡送给别人、在二手网站上卖掉，都可以。
若持卡人只是离开奥克兰一段时间，不用过于担心卡中的钱有效期的问题，新西兰毕竟是资本主义社会，对于私有财产的保护是到位以及合理的，充值进入奥克兰公交卡中的金额，有效期为6年，如果6年后还不花掉，那么奥克兰交通局就“笑纳”你的余额啦；另外，余额失效的同时这张卡也会在系统中被注销掉，不能再使用。
官方的英文原文：The AT HOP card (including any HOP money or Products loaded on the AT HOP card) will expire if the AT HOP card is not used, no refund is requested, the AT HOP card is cancelled, or no Products are loaded onto the AT HOP card for a continuous period of six years. When an AT HOP card expires, any HOP money or Products remaining on the AT HOP card will be forfeited and become our property on and from the date the AT HOP card is cancelled. In this instance you may contact us and we will put HOP money on to another AT HOP card purchased by you.
