First of all, Lighthouses are an attraction. Most of them are not any longer in use. They can be visited from outside only, occasionally from inside. Some of the Lighthouses have a dramatic location, some a touching history and others are simply beautiful.
Best light for a good shot is in the morning or at sunset and there are fewer crowds. The opening hours of the lighthouse are from 9 a.m. to 5 p.m. Less crowded early morning.
Best seasons are late spring, summer and beginning of autumn (October/November until March). Rain can occur more often in "winter" - the "rainy" season.
Best light for this picturesque lighthouse between afternoon and evening. The clouds at Mount Taranaki at the back built up before midday and may disappear in the evening. The lighthouse is open by appointment only: Historic Cape Light and Museum
Best months with less precipitation from January to April. Most rainfall from June to October with its peak in October. Mild and pleasant temps on average around 20°C from December to April.

The Sapphire Coast has an oceanic climate. Winters are mild, windy and drier with an average day temperature of 7°C. Usually, it's quite hot during summer with a day temperature up to 30°C. Most precipitation between spring and summer. The water temperature is refreshing with more than 20°C from summer until autumn (Dec-April). Autumn still is still pleasant.
Whales migrate along the coast in late winter and spring between May/June until November. It's an excellent spot to spot migrating whales.
The photogenic Low Head Lighthouse is not open to the public. What makes this lighthouse special is the kind of foghorn which is one of only two existing ones in the world. It always only sounds at noon on Sundays. If you plan to visit the penguins during the evening at Low Head have a look to the lighthouse as well but it's not worth a detour.
Lighthouse and area are open until 5 p.m. Afterwards the whole area is closed. There isn't any chance to watch the sunrise or sunset at this remote and dramatically located lighthouse.
