Mooar took up a three-year contract with the Scarlets, replacing another New Zealand Wayne Pivac, who is now coaching Wales, at the start of the season. The side have won eight of 11 games since he took charge.
The Scarlets club announced earlier that they were in conversations with New Zealand Rugby.
"Discussions between the Scarlets and New Zealand Rugby are at an early stage and we are unable to comment further until those discussions are concluded," it said.
Mooar, pictured, told walesonline.co.uk, "It's humbling to be in the conversation. We can't really add anything more because there is nothing more to add to it.
"The question has been asked, we are grown adults and are having responsible conversations and things will pan out.
"I am torn, yes, this is tough and both options are outstanding. We will just have to keep the conversations going," he said.
Mooar said he was enjoying his position with the Scarlets who beat Bayonne at the weekend 46-5 in the European Challenge Cup.
He did say that it would not be difficult to complete his season with the side should he be released from his role as the next All Blacks Test was against Wales on July 4.
"The focus will remain. We have set a vision and scene and are working together and our noses in the same direction. I am here and we are doing a great job with the group, and they are working for each other and it's great.
"What you saw tonight is the 'we' in our club is a hell of a lot bigger and stronger than me," he said.
"The way the boys pulled together and put a performance on was outstanding. It's a tight group, we have had a great week and are excited about what is coming up. I am proud to be here," he said.
Scatlets centre Steff Hughes, the side's captain, said Mooar was 'a great bloke' and that all the players enjoy working with him.
"Nothing is going to change, we are just focusing on next week and moving on from there," he said.
