"This company has done lots but this is not a growth story. The owners have squeezed a lot out of this company but it will provide a yield. We believe the best time to own Z is in the first two years."
New Zealand's equity market had been flat lately, in comparison to others, and Curtayne believed people had been holding back their money to invest in Z and Meridian.
Z was relatively regulation-free, unlike the electricity market which faced possible centralisation by a future Labour-Green government.
Management was making proven market inroads where former owner Shell took "its eye off the ball".
"It is a New Zealand company garnering Kiwi support. If more majors outgrow enthusiasm for the small, low-growth market, Z could be a major beneficiary."
The 17 per cent stake in Refining New Zealand Z would buy was a partial hedge against the admittedly lower-risk chance of a rise in refiner margins and dealt Z into a strategic asset, particularly the 168km Marsden to Auckland pipeline, he said.
In some respects, the refinery tie-up was necessary, regardless of what Morningstar thought were relatively unattractive cash flows to ensure continuity of supply. Z had also driven returns on invested capital back above the cost of capital.
Longer term, Taylor was forecasting a 10.3 per cent return on invested capital from 2016, healthy but not sufficient to drive a competitive advantage.
