Given our recent history of short term demand peaks, sooner-than-expected tightening of supply, along with any number of economic landscape variables, the need for accurate and readily accessible production and consumption data is essential for industry participants.

Tracking production

Gas production in New Zealand is based entirely in the Taranaki region. Approximately 17 wells and the largest single source of energy in New Zealand, the Pohokura field, are responsible for output of around 180 PJs per year. The chart below shows the gas output from most major gas fields in New Zealand.

The chart below shows the gas output from most major gas fields in New Zealand.  

Please note that not all data is publicly available as some gas is transported through private pipelines. It is for this reason that the Kapuni field is notably absent from these charts. We are not confident that the publicly available information sufficiently captures the activity at Kapuni. 

For information relating to some of the production down-turns in the chart please visit our Industry Notifications page. Since July 2019 producers have been voluntarily disclosing planned and unplanned production outages. 

The data used to make the charts can be downloaded here.

Daily Gas Production by Major Fields

Over the past couple of years the Pohokura field has experienced considerable decline as the field ages.

Meanwhile over the past year the Maui field has significantly increased its production due to successful infill drilling.

Tracking consumption

In New Zealand there are four major industrial gas users – Methanex Motunui, Huntly Power Station, Methanex Waitara Valley and TCC. This chart shows their daily consumption from January 2019 to now.  

Daily Consumption by Largest Users

In May 2021 Genesis announced a deal to purchase gas from Methanex over the winter of 2021. This can be seen on the above chart, with dramatically lower consumption from Methanex and higher consumption from Huntly between June and August 2021.

Over the past week Methanex’s Motunui consumption has increased to over 180 TJ/day.
