New Zealand shares fell the most across Asia as Z Energy led the market lower for another day amid rising oil prices, growing competition and the threat of increased regulation.
The S&P/NZX 50 index dropped 108.33 points, or 1.2 per cent, to 8,802.26. Within the index 39 stocks fell, nine gained and two were unchanged. Turnover was $115.6 million.
The local market posted the biggest decline across Asia-Pacific. Australia's S&P/NZX 200 index was down 0.2 per cent in afternoon trading, Hong Kong's Hang Seng fell 0.3 per cent, and Japan's Topix was down 1.1 per cent.
Z Energy led the local market lower, falling 3.9 per cent to $6.10, the lowest close since February 2016. The share price has dropped 11 per cent this week after the transport fuels company reported lower petrol volumes as oil prices rise. At the same time, it's facing increased competition from low-cost operators such as Waitomo and has the government threatening regulatory intervention.
Matt Goodson, managing director at Salt Funds Management, said the share price is under pressure from the operational data showing lower fuel volumes and what impact a Commerce Commission study into the fuel market will have on margins. Those regulatory powers are yet to be passed into law.
