Kia ora, I have just closed a major tourism business in Rotorua so completely empathise. The Domestic market is clearly going to be vital to your survival and as a small business I would recommend partnering up. Other industry businesses will have similar challenges so try to seek out a compatible partner(S). Through a collective you may be able to see your sales and marketing budgets go further. Rotorua is well placed Geographically to benefit from Domestic Tourism and Corporate travel given its proximity to Auckland and this market is where your focus should be.
On the HR front if your referring to recruitment then employment contracting in the future is going to be critical. You must aim for flexibility in your labour force. You will have a challenge in getting any employee to regain faith in their employer and that journey is going to be rewarding.

(Happy to help in more detail)

Kia kaha!
