#Past work  Microseismicity has been observed at Rotokawa since the start of deep injection in 2005 \cite{Sherburn_2015} and at Ngatamariki since injection operations began in 2012 \cite{Sherburn&Bourguignon_2013}. At Rotokawa, the largest portion of microseismiciy since 2012 has been located in the southeast portion Some  of this activity is accounted for by background, natural seismicity associated with  the field as discussed in \cite{Sherburn_2015}, geothermal fields' location  within the polygon shown in \ref{Figure1}. Much tectonically dynamic TVZ. However, a much larger part  of this seismicity the microseismicity at Ngatamariki and Rotokawa  is likely related due  to changes in  the Central Field Fault which divides the injection reservoir associated with deep fluid injection. Critically stressed  and production areas at Rotokawa favourably oriented fractures within  and acts as a barrier adjacent  to cross-strike movement the geothermal resource can be activated by both pressure changes induced by power plant operations as well as thermal contraction  of the hot  reservoir fluids rocks as the cooler condensate and brine is injected  \cite{Sherburn_2015}. At Ngatamariki, two very distinct, clusters of microseismicity are observed, one in Rotokawa,  the North largest portion  of the field and one further south \cite{Sherburn&Bourguignon_2013} \cite{Sherburn&Bourguignon_2014} \cite{Sherburn&Bourguignon_2015}. The northern cluster microseismiciy since 2012  has beenobserved in the northern injection area surrounding wells NM8 and NM9 at a between 1.5 and 2.5 km below sea level whereas the southern cluster is generally  located between the injection area associated with NM10 and NM6 and in  the production area for southeast portion of  the field surrounding NM5 \cite{Sherburn&Bourguignon_2015}. This as discussed in \cite{Sherburn_2015}, within the polygon shown in \ref{Figure2}. Much of this seismicity  is likelyassociated with a structure  related to the Aratiatia Central Field  FaultZone  which strikes SW-NE accross divides  the southern end of the Ngatamariki field injection and production areas at Rotokawa and acts  as has been modeled by \cite{buscarlet2015reservoir}. Events have been observed in roughly equal numbers in both clusters \cite{Sherburn&Bourguignon_2013}. a barrier to cross-strike movement of reservoir fluids \cite{Sherburn_2015}.  1. Rotokawa  * Locations normally At Ngatamariki, two very distinct, clusters of microseismicity are observed, one in the North of the field and one further south \cite{Sherburn&Bourguignon_2013} \cite{Sherburn&Bourguignon_2014} \cite{Sherburn&Bourguignon_2015}. The northern  cluster has been observed  in the northern injection area surrounding wells NM8 and NM9 at a between 1.5 and 2.5 km below sea level whereas the southern cluster is generally located between the injection area associated with NM10 and NM6 and the  production area within for the field surrounding NM5 \cite{Sherburn&Bourguignon_2015}. This is likely associated with a structure related to the Aratiatia Fault Zone which strikes SW-NE accross  the 'RK04, RK05, RK20' triangle southern end of the Ngatamariki field as has been modeled by \cite{buscarlet2015reservoir}. Events have been observed in roughly equal numbers in both clusters \cite{Sherburn&Bourguignon_2013}.
