Air New Zealand banned Anjela Sharma from flying for a year, after a dispute arising from an incident at the Nelson Koru Club.

A Nelson lawyer says she is exploring her legal options following a judgment upholding a travel ban imposed by Air New Zealand.

Anjela Sharma was banned from flying on the national carrier for a year following a dispute over entry to the Koru Lounge at Nelson Airport in 2018.

Three weeks after receiving the ban in July 2019, Sharma filed a proceeding against Air New Zealand over the ban, as well as a mandatory interim injunction to immediately remove it.

At the High Court in Auckland on Monday, Justice Paul Davison dismissed the application and also declined an application to move the proceeding to the High Court in Nelson.

When asked by Stuff about her reaction to the decision, Sharma said she did not want to comment at this stage, other than to say she was currently assessing her options with her legal advisors.

In her statement to the court, Sharma said she had been a regular flyer with Air New Zealand since 1980, and had been a member of the Koru Club for several years.

She said she was dependent on Air New Zealand's service for work-related travel, as well as for maintaining contact with family.

The dispute occurred on December 1, 2018, when Sharma and her family were about to fly out to India via Auckland.

Sharma said, on her understanding, their business class tickets entitled the family to use the Koru Club Lounge at Nelson Airport.

RICKY WILSON/STUFF Sharma said she said she was dependent on the national carrier for work-related travel, as well as for maintaining contact with family.

She said they had been permitted to enter the Koru Lounge during a two-hour wait until their departure. After an enquiry from a second staff member, she had shown them her family's business class travel documentation on the Singapore Airlines flight to India and it was accepted they could remain there while waiting for their flight to depart.

However, two of the staff members had claimed Sharma and members of her family had acted in a loud, disruptive and intimidating manner in their dealings with the Koru Lounge hostess.

While the family were still in India, Sharma received a warning letter from Air New Zealand on December 21 regarding their behaviour at the Koru Lounge.

In March 2019, Sharma sent an email to former Air New Zealand chief executive Christopher Luxon disputing there was any justification for the warning letter.

Sharma continued to send communication and tried to check-in on a flight and accused a Nelson staff member of lying and being "on a venomous mission" against her, the court decision stated.

An email was sent to Sharma on behalf of Luxon stating her correspondence had been "distasteful and insulting" – leading to the 12-month ban imposed in July 2019.
