Lees was told in late March 2020 that her position had been disestablished as a result, even though she performed other health checks.
She took her case to the Employment Relations Authority (ERA), which has found her dismissal was unjustified.
It said Triton failed to properly consult with Lees before deciding to make her redundant.
The authority said the "unusual circumstances" of the lockdown did not absolve Triton of its legal obligations to its employees.
Lees told ERA redundancy had "totally ruined" her and she had been unable to find permanent work.
She was awarded $17,000 in compensation and almost $15,000 in lost wages.
