I thought I'll share my experience to other users who plan on going onto this plan. We are flat of 5 and we consider our self's heavy internet users.
Paying $104 a month. We are located in Riccarton a suburb in Christchurch.
Below are my snyc stats from the orcon modem which we decided to hire at cost of $4/M. So far the modem has handled large amounts of data; this includes several computers gaming at once, other computers browsing or steaming 1080p videos on youtube and other streaming sites like vimeo.

Of course after 6pm we have noticed slower speeds in downloading from international servers, however we were still able to stream at 1080p and gaming was still fine.
Downloading from a seedbox from holland we were able to reach download speeds of 1.1 to 1.2mbs consistently, in the evening slowed to 700kbs.
P2P is also slowed in the evening but this is hugely varied. Excellent during the day and very early in the morning.
The ping is constant to LA servers at 200 to 210ms most times of the day.
Has any other users here experienced an overall good internet connection from this new plan? I think this plan is great. Im not very computer originated, but i hoped i gave a good insight of how this plan works.
