Fine weather for much of the South Island
A clearing sky should reveal fine spells and even sunshine for southern centres on Tuesday, as a short work week kicks off for many.
Northeast winds should increase in the afternoon for Christchurch, with the city expected to reach a high of 16 degrees Celsius shortly after lunchtime, according to MetService.
Planned night-works in the Lyttelton Tunnel could affect driving times between the port and Christchurch. From Tuesday the road would be down to one lane from 9pm to 1am, and 2am to 5am, and the New Zealand Transport Agency (NZTA) has said delays were expected.
Amid fears of a grim winter for Kaikoura businesses, State Highway 1, the town's main access route from Christchurch, remained closed on Tuesday after a large slip on April 15. An update on the road was expected on Wednesday.
Motorists wanting to reach Kaikoura were advised to take the inland road via Mt Lyford and Waiau. NZTA advised caution on this alternate route due to high traffic numbers and ongoing road works following the November 2016 earthquakes.
The town should expect some morning showers, clearing in the afternoon with fine spells. A high of 15C.
Further south, morning cloud in Dunedin should clear to reveal a fine day with a high of 14C.
On the West Coast, a fine day was forecast aside from evening cloud. Light winds in Greymouth and a 17C high.
Westport was set to take the cake for high temperatures on Tuesday, expected to reach 18C by mid-afternoon. A fine day with a chance of showers and southwest breezes.
At the top of the South Island, Nelson should expect a high of 17C as morning cloud burnt off. A chance of rain in the evening, but otherwise a fine day with light winds.
Blenheim was forecast for similar conditions on Tuesday. A fine day following morning cloud, light winds and a high of 17C.
