New Zealand's NZX 50 Index dropped nearly 1 per cent on global trade news, with Synlait Milk and Sky Network Television suffering while CBL remained in a trading halt as its administrators gained more time to consider its finances.

The NZX 50 fell 85.45 points, or 0.99 per cent, to 8,515.36. Within the index, 39 stocks were down, seven were unchanged and four rose. Turnover was $106 million.

Global equity markets have fallen on concerns a trade war may emerge after US President Donald Trump announced tariffs on Chinese goods and China retaliated, announcing plans for reciprocal tariffs on 128 US products. At 5:20pm, Japan's Nikkei 400 was down 3.3 per cent, the S&P/ASX 200 had dropped 2 per cent and the Hang Seng was 2.8 per cent lower.

"Our market has behaved quite nicely all things considered, and that's the nature of our exchange, which tends to have a lot of defensive, utility-based stocks which tend to outperform when things get a bit rough," said Peter McIntyre, investment adviser at Craigs Investment Partners.


"Compared to our friends in Asia we are performing very well. Trump certainly has set the market alight again - even though there is a 60-day treaty before any of this potentially gets enacted, it has put the market on edge."

Synlait was the worst performer, falling 4.5 per cent to $8.70. That still leaves the stock up 6.6 per cent this week, after it surged on the release of its record first-half results on Wednesday.

Sky TV dropped 3.3 per cent to $2.32, Westpac Banking Corp fell 2.7 per cent to $30.85, and A2 Milk Co declined 2.6 per cent to $13.73.

CBL remained in a trading halt at $3.17. The company's voluntary administrators have postponed the creditors' watershed meeting to gather more information and hired Goldman Sachs as an adviser.

Auckland-based CBL appointed KordaMentha voluntary administrators on March 2 after the Reserve Bank sought an interim liquidation of its New Zealand supervised arm and the Central Bank of Ireland made a similar move against the insurer's European division.

The second meeting of creditors gives them the choice to resolve that a deed of company arrangement be executed, resolve that the administration should end, or appoint liquidators. It must be held by May 18, and KordaMentha must release a watershed report to creditors and the market by May 11.

"It just creates more uncertainty for shareholders," McIntyre said. "Obviously they'll be looking at all ways to obtain value for those shareholders and potentially a trade sale somewhere along the line. it's been a drawn-out saga and hasn't been a good example for the stock exchange either."

NZX was the best performer, up 0.9 per cent today.


Meridian Energy rose 0.9 per cent to $2.945, Port of Tauranga gained 0.2 per cent to $5 and Genesis Energy was unchanged at $2.395.

"Meridian, Genesis and Ports of Tauranga are carrying dividends, so they're being supported in today's market," McIntyre said. "Income is an important part of investor returns, so a lot of investors are looking to continue to buy those stocks for the dividends."

Auckland International Airport gained 0.3 per cent to $6.20. It released its February monthly traffic update showing domestic passenger numbers lifted 7.5 per cent and international passengers rose 6.7 per cent.

"International passengers and domestic passengers continued to be strong, the concerning thing is with regards to Australia which puts a dampener on the update," McIntyre said. "That weighed on the stock earlier today. It's been weaker this month, it is a quality company that has come off its highs quite considerably."
