The Tui oil field operator off the South Taranaki coast has told a consensus hearing, if no further development is made, that the resource could be uneconomic by the end of next year.
The Environmental Protection Authority is listening to marine consents and a marine release consent request from Tamarind Resources in New Plymouth.
Tamarind is based on Malaysia asking for permission to drill up to five side track development wells and emitting the trace elements of harmful substances of leech drainage.
The company's representative, Lauren Wallace, told the hearing that the Tui Field had a proven track record of successful abstraction.
"The field has produced more than 40.7 million barrels of crude oil since its production began in 2007."
But that could change soon, says Ms. Wallace.
"If no further activity is carried out in the field, production rates of the field are likely to be uneconomic by the end of 2019 and the decommissioning of assets will be necessary."
Ms Wallace stated that the objective of the side track fountains was to reach 7.5 million tonnes of future oil reserves from Tui.
"Tamarind believes that the successful outcome of the proposed activities would extend the life of Maes Tui up to 2025."
At the end of 2016, the government received $ 573 million in royalties from Fai Tui and it was anticipated that an additional $ 10.3 million would be up to 2020.
Ms Wallace said Tamarind believed that the environmental impact of his planned work program would be "incredible to minor".
"The applications will not mean that any new springs are drilled to bed and the sea or any new structures installed at sea."
Side track development joins a good surface location with equipment designed to divert from existing excavation and find oil in another zone.
Ms Wallace said at the hearing that a request for a marine discharge consent was requested with "insufficient notice" for offshore drilling rig deck drilling that could include tracing elements of harmful substances.
The EPA has received 124 submissions on Tamarind's applications, and 108 object to granting consent while 12 in favor.
Three presenters want conditions applied if the applications are successful and one was neutral.
The vast majority of those who objected to the applications completed, 95, a presentation form prepared by Climate Justice Taranaki.
In its written submission, the environmental group argued that Tamarind's impact assessment did not provide enough detail to enable the EPA to understand the effects on the existing environment and interests, as required by the Unique Economic Zone Act 2012 .
"The information provided is insecure and inadequate and the Minister must support and protect the environment," Taranaki's Climate Justice wrote.
The group reported that the cumulative effects of Tamarind and other industrial activity in southern Taranaki Bight on marine species had not been properly assessed.
"The risks to endangered and endangered species are unacceptable," he said.
In his presentation, Te Kāhui from Taranaki said that I had been in discussions with Tamarind.
He asked that if the application was successful, Tamarind was committed to working with Taranaki to develop environmental indicators using the Te Ao Māori perspective and western science.
He also wanted Tamarind staff to have cultural training and the company committed to an annual meeting with Taranaki iwi.
Te Korowai of Ngāruahine Trust recently wrote to the EPA to update her relationship with Tamarind.
In the letter, South Taranaki said that she had met Tamarind to address Ngāruahine's concerns about the lack of coverage paid by the company to her / her.
It was reported that Tamarind and Te Korowai were developing a Relationship Agreement and the company was committed to taking part in discussions with Ngāruahine hapū.
In October, the EPA gave such a request to a marine discharge consent to New Zealand OMV.
