The escalation of construction costs means the cost of Napier's new aquatic centre is costing an extra $3000 per day.
Napier City Council will meet on Tuesday to discuss the new aquatic centre, as part of their Strategy and Infrastructure Committee meeting.
The new pool is already the most expensive project NCC has ever undertaken, and is due to cost more than $41 million.
The meetings agenda states that the escalation of construction costs was estimated to slow at the end of 2018 and flatten at the start of 2019, but this had not eventuated.
The result is that construction costs are increasing about 3 per cent each year, translating to about $3000 a day for the pool project.
