Kiwi overseas travellers face volatile prices, with international airfares up 7.2 per cent last month compared to March.
International fares had been falling as more competition entered the market over the summer but spiked last month, according to Stats NZ figures.
April is when peak summer capacity comes off New Zealand routes as airlines deploy planes to the northern hemisphere.
But the annual trend is good for travellers. During the past 12 months, international prices have fallen 20.5 per cent.
And while domestic fares spiked earlier this year, they are down 5.1 per cent between March and April and down 6.9 per cent over a year.
