Yes – use is having a negative impact
Human presence causes a significant drop in the probability of a successful transit to or from their nest, and significantly increased the time penguins spent alert and decreased the time spent preening.
On Enderby Island, tourists approached to a median minimum distance of 27 m, where the probability of disturbance is 0.65, and 39% of tourists approached to a minimum distance of < 21 m, where the probability of disturbance is > 0.87. At the current minimum approach distance (5 m), the probability of disturbance is 0.99. These disturbance probabilities imply that a new minimum approach guideline is warranted. Due to the small size of the area (the length of penguin alley is approximately 70 m), reducing the probability of disturbance to near-zero (a distance of c. 50 m) may be impractical, but our results can help managers to decide on and justify a distance that is acceptable. At 40 m for example, the probability of disturbance is still low (0.15) so this distance may be an acceptable compromise between minimising disturbance and practical limitations.
Yes, considered unsustainable
Actually, authors implied opinion indicates that use is not sustainable under current conditions but may be sustainable if regulations were stricter. However, if "No, sustainability not determined" was ticked, database would not allow adding of any details
Classified as ‘Endangered’ by IUCN and the New Zealand Department of Conservation (BirdLife International 2017), the population is estimated at less than 2,000 breeding pairs, with 60% of the population thought to occur in the subantarctic. Studies on mainland Yellow-eyed Penguins have shown it is one of the most sensitive penguin species to human disturbance. The presence of tourists decreases the likelihood an adult will come ashore to their nest, increases transit times to and from the nest and increases the likelihood of nest abandonment. This delay increases the amount of food digested before regurgitation, resulting in less food available for the chicks.
Tourism is strictly controlled at the study site with a no-stopping zone. On Enderby Island, tourists approached to a median minimum distance of 27 m, where the probability of disturbance is 0.65, and 39% of tourists approached to a minimum distance of < 21 m, where the probability of disturbance is > 0.87. At the current minimum approach distance (5 m), the probability of disturbance is 0.99. These disturbance probabilities imply that a new minimum approach guideline is warranted.

Authors state: "the negative impact of human presence shown in this study indicates the importance of minimising the number of human-penguin interactions. This can be done by keeping the total number of tourists visiting the island to low levels, regulating the timing of tour boats landing and departing to avoid peak penguin activity, and limiting the number of tourists ashore at one time. In addition, regulations such as a suitable minimum approach distance are important for reducing the disturbance during a penguin-human interaction. Minimum approach guideline needs to be revised if the probability of disturbance is to be reduced", where any guidelines should be based on and validated through scientific research

Yes, recorded as negative
Authors state: "results of this study indicate that human presence has an impact on behaviour of the subantarctic Yellow-eyed Penguin. An increase in the time spent alert may indicate an increase in the levels of stress hormones (such as corticosterone). Increases in base-level corticosterone may, over the lifetime of the bird, decrease fitness and survival. An increase in transit time and the number of aborted transits is likely to decrease the food available to chicks, which may lead to decreased fledgling weight. Low fledging weight leads to decreased juvenile survival, meaning that lower fledging weights can have long term population consequences. "
