The city's seeing a lull in building activity, with fewer consents being issued for new dwellings.

Just 19 planned homes were signed off in Dunedin last month, down from 33 in March and 50 in February.

That's a 33% drop compared to this time last year.

Nationally more houses are being consented although the construction boom is easing slightly.

The most development remains in Auckland, Canterbury and Waikato.

Overall the number of new dwellings being consented annually is at an 11-year high.
