From the moment your points are credited, your Neuland points are valid for 365 days.
If no more points are added, your points will expire unless you convert them into shopping vouchers before then. (Don't worry: We will remind you in time with an e-mail message.) If new points are added within the 365 days, all Neuland points will be validated again for another 365 days from that point on.
With new points you also extend the validity of the old ones.
