There were opportunities for greater collaboration with Singapore Airlines.
"Air NZ has had a frosty relationship in the past given their combined Ansett history, however with Singapore Airlines' management fairly new and with a new CEO in Christopher Luxon, we think there may be opportunities to revisit this relationship to facilitate greater connectivity into the rest of Asia and arguably continental Europe, but without having to invest substantially more capital on what has traditionally been a lower margin part of the network."
The New Zealand domestic market remains the only area of concern for Air NZ given premium weak demand such as that for Government travel, and Jetstar adding more capacity here.
"However the ongoing transition across to a more fuel efficient A320 fleet should see Air NZ maintain its profitability in its key home market." The airline's shares were undervalued, the report says. Macquarie estimates a book value of $1.60, and its target price $1.82, well up on the closing price of $1.28 yesterday.
Air NZ's 20 per cent stake in Virgin Australia is estimated to be worth 22c to its own share price.
Luxon had impressed analysts with the urgency he was working to improve domestic and international services, the report says.
