I have just returned from doing the Tongariro Crossing in the North Island.
This company provides a guided crossing in the winter, when the snow requires a guide for all of those but the most experience. In the summer they will take you to the base camp and pick you up on the other side.
As oppose to other agencies they have got a concession from the maori iwi that allows them to do the full crossing. Be aware of other agencies that may take you to the top but you will have to return the same way back

AdriftNZ is a specialist guiding company and is the only company currently operating daily with a concession to guide during summer and winter on all tracks and routes in the Tongariro National Park including the Tongariro Alpine Crossing. This gives AdriftNZ the unique opportunity to offer their customers tracks and scenery others are not authorised to guide. AdriftNZ can pick and chose the track best suited to the conditions of the day and for the best enjoyment of their client. Last year AdriftNZ was contracted to guide Stuart Franklin photographer for National Geographic, whose photo essay is in the July 2009 issue. www.adriftnz.co.nz
