Thaks JandM for your response. I got below mail from immigration NZ.
"Thank you for your response. We do appreciate your difficult circumstances. Unfortunately, as detailed in the letter, we have no legal authority to extend your current visa, and there has been no ministerial intervention in order to allow Immigration New Zealand to extend the validity of expired Job Search work visas for offshore applicants. There has been no change to the immigration instructions currently in place, and we are unable to make exceptions to residence instructions.
If you decide to withdraw the application under the current circumstances, we will consider your eligibility for a refund in this case. However, please note that you will not have the right to appeal if you choose to withdraw.
Otherwise, if you chose to proceed with the application in order to later exercise your appeal rights, we will continue with the assessment of your application. I note that you have until 29 August 2022 to provide any further submissions."
