The Auckland LEGO User Group (AuckLUG) is holding its annual Brick Show this weekend. Details about how to purchase tickets in advance (they are cheaper if bought online) can be found at http://www.aucklug.co.nz/. Entry for children under 4 is free.
In the meantime, here is an image of the poster we are using to advertise the show
So if you are in Auckland over Labour Weekend and were wondering what to do to pass the time, visit the Brick Show and spend an hour or two (and then some?) there.
