Lane closures remain in place in and around the fire-struck New Zealand International Convention Centre, owned by SkyCity, as fire crews still monitor for hotspots at the site.

Nelson St is open for two lanes - which includes the cycleway and footpath on the left-hand side.
Two lanes on Hobson St are also being made available and which includes a bus lane and left-hand side footpath for pedestrians.
Only buses are being allowed on Wellesley St between Nelson and Hobson streets at this time.
"While the roads will be reopening, there will still be significant delays for those who are driving," an AT spokesman said.
"Taking public transport, carpooling, walking or cycling will help reduce congestion in the city centre. Once again, thank you for all your patience and understanding over the past week."
