The seismically active southern end of the Taupō Rift beyond Mount Ruapehu has a number of mainly east to west orientated termination faults where the western wall Raurimu Fault and eastern wall Rangipo Fault (Desert Road Fault) terminate in the Ruapehu Graben, of the central North Island of New Zealand. In a multi-fault rupture event there is the potential for the earthquake being of  magnitude. 

The faults can be classified as belonging to three normal fault sets:
 Ruapehu Graben NNE‐trending faults
Raurimu Fault - see separate article
Rangipo Fault (Desert Road Fault) - see separate article
 Mostly uncharacterised faults under Mount Ruapehu
 Ohakune‐Raetihi fault set that is  wide of E‐W to ESE‐WNW‐trending faults
 Ohakune Fault
 Raetihi North and  South faults
 Waipuna Fault
 Oruakukuru Fault
 Rangiahu Fault
 Maketu Stream Fault (Maketu Trace)
 Karioi fault set that is  wide of NE‐trending faults
 Karioi Fault
 Wahianoa Fault
 Snowgrass Fault
 Shawcroft Road Fault
 Moawhango Fault

Ohakune Fault 

This most northerly of the cross faults extends  from northwest of Tohunga Junction into the Rangataua Forest. At Tohunga Junction it crosses the Raurimu Fault with a complex series of faults. The fault to the west of this junction region has  of vertical displacement and to the east there is only . This downthrown to the south normal fault has been active for over 18,000 years and has a dip-slip displacement rate of /year.

Raetihi faults 
The E - W trending  of the Raetihi North Fault is downthrown to the south while the  Raetihi South Fault is downthrown to the north so they have a small graben between them. The Raetihi South Fault possibly continues along the Mangahowhi  Stream for up to . Displacement rates based on an age of 18,000 years for the scarps are /year for the Raetihi North Fault and /year for the Raetihi South Fault.

Waipuna Fault 
South of the Raetihi faults, the most western of the faults discussed, the  Waipuna Fault is  downthrown to the south and extends  from the Waimarino Forest to intersept the Karioi Fault. The displacement rate might be /year but this has an error of the same order.

Oruakukuru Fault 
The Oruakukuru Fault to the south of the Waipuna Fault commences at State Highway 4 (New Zealand) close to the upper Mangawhero River extending  also intersects the Karioi Fault and has a displacement rate of /year.

Snowgrass  Fault 
The south east Taupō Rift is associated with a  northeast trending dome south of the Ngamatea Swamp where the Rangipo Fault terminates. The 
Snowgrass Fault on the northern side of this dome is a downthrown to the south normal fault that is displacing at an estimated /year.

Shawcroft Road  Fault  
The  Shawcroft Road Fault cuts across the Rangipo Fault line just to the north east of the Waiouru Military Camp and is displacing at /year.

Karioi Fault  
The  normal Karioi Fault is parallel and to the north of the Shawcroft Road Fault and is  long with a summed displacement for its two strands of /year.

Wahianoa Fault 
The Wahianoa Fault is a northeast-striking  presumed normal fault across the southeast flank of Mount Ruapehu extending at least  from the Ohakune Fault towards the Rangipo Fault and the Upper Waikato Stream Fault with a displacement rate of /year.  
It has been postulated that it has the potential to do a whole fault rupture at the same time as whole fault rupture of the Rangipo and Upper Waikato Stream faults which would result in a  event rupturing  by an average of
