Jasons Travel Media made $1.2 million in the six months to the end of September, 1% less than in the same period last year.
Revenue fell 3.5% to $8.2 million.
Jason's chairman, Geoff Burns, says reduced visitor spending has created uncertainty for the company's advertising clients.
The company's Australian business remains challenging, but revenue from its South Pacific guides and maps held steady, and improved for its New Zealand guides.
Mr Burns says if market activity remains stable, the company's full year profit will be similar to last year's.
The company is not paying an interim dividend, to aid the development of its new web-based business model.
